Tools
| Tool | Description | Behaviour |
|---|---|---|
| goodearth_account_statement | Generate a patron's account statement at this operator. Returns the patron's purchase history, active credit tranches, per-tool usage breakdown, and recent daily usage logs. This is the patron's spending account — not the operator's Authority tax balance. Free — no credits consumed. Proof of npub ownership is required to prevent statement-scraping of arbitrary patrons. | Not declared |
| goodearth_account_statement_infographic | Generate a visual SVG infographic of your account statement. Returns the same data as account_statement, rendered as a dark-themed SVG graphic with balance hero, metrics cards, health gauge, tranche table, and tool usage breakdown. Costs 1 api_sat per call. Proof is verified by ``debit_or_deny`` before any cost is incurred. | Not declared |
| goodearth_adoption_status | Check this operator's adoption-request status at a chosen Authority. Free. Polls the Authority MCP-to-MCP for the status of this operator's request (pending / approved / rejected / provisioned). | Not declared |
| goodearth_almanac | The sky's own record for this ground — normal, actual, and what is coming. Degree days say what the season is doing to the plants. This says what the season is doing: temperature, dew point, rain, wind, sunshine and day length, each against what is normal here, what has actually happened, and the fortnight ahead. Plus the sun and moon, which are astronomy and so are computed exactly rather than forecast. Growers read these together with the heat. A week of high dew points is disease weather whatever the degree-day total says, and a dry August is an irrigation decision that heat accumulation cannot make for you. One call covers every measure — three upstream requests regardless. | Not declared |
| goodearth_block_item_list | What you grow, watch for, or saw on a plot — a page at a time. `as_of` is how a past season answers: the record as it stood that day, rather than as it stands now. Sorting and searching happen in the database, over as many rows as the block holds rather than the page you are looking at. | Not declared |
| goodearth_block_item_save | Record what you grow, watch for, saw, or hold seed for on a plot. A whole batch in one call, because an afternoon in the field produces several notes at once and each one should not be its own fare. | Not declared |
| goodearth_block_list | The ground you have saved, with its bounds. The blocks themselves and nothing else — what grows on them, what you watch for, and what you have seen are their own listing, so this answer stays the same size whether you farm one plot or forty. A grower who has saved nothing gets the worked example, marked as such, so there is always somewhere to stand. Blocks can overlap — a meadow drawn inside the farm that contains it is two blocks, each answered for its own ground. Read an overlap as intent, not as one outline being wrong. | Not declared |
| goodearth_block_save | Save a plot of land, so every other tool can work it by name. Its area and sample count are measured here from the bounds you give, and returned — they are facts about the geometry, so there is nothing for you to keep in step. Blocks may overlap or nest. A grower who saves the whole farm and then the meadow inside it has asked two questions about two pieces of ground, and both are right; the overlap is not a drawing error to correct. | Not declared |
| goodearth_calendar_dataset | Compute this block's dated season as a dataset, and store it for publishing. Every dated thing this block knows about: crop targets, pest stages, wildlife and husbandry dates, the frost record, and your tasks. Returned as structured rows — a calendar is one rendering of them, and a caller wanting a table or a notification wants the same data. An iCalendar rendering is stored alongside under a feed token, which the Good Earth site serves at a subscribable URL. Point any iCal or Google Calendar client at it and the season appears next to the school run and the market stall, which is where a grower will actually see it. This is the computed act: it reads the weather feeds and rebuilds everything. Pass the same token again to recompute in place — subscribers keep their subscription and the events update rather than duplicating. Nothing is passed in but the block: what it grows, what it watches for and what is due are read from the record. That is what makes a refresh safe — while those collections travelled as arguments, nobody could recompute an existing feed without knowing what had been handed to it the first time, so a refresh silently published a smaller season than the one it replaced. | Not declared |
| goodearth_calendar_fetch | Read a stored calendar dataset by its feed token. This exists for the Good Earth site, which serves the subscribable URL: a calendar client speaks HTTP and knows nothing about MCP, JSON-RPC or npub proofs, so the site fetches through here and renders the response as text/calendar. The unguessable token is the credential — there is nowhere in an iCalendar subscription to put a proof. Serving is a separate act from computing, and every read is counted so the operator can see how hard a feed is worked. | Not declared |
| goodearth_calendar_list | The calendar feeds you have published, and how often each is polled. | Not declared |
| goodearth_calendar_revoke | Stop publishing a feed. Subscribers stop receiving updates. Free. | Not declared |
| goodearth_calibration | Turn a block's own field reports into a correction on the model. Every other tool here answers from a 9 km grid refined by a physical terrain model. What that cannot know is the part that makes a farm particular — the hedgerow, the pond, the outlet the cold air drains through. Your observations measure exactly that gap. Returns two corrections, kept separate because they fix different things: a bias in *heat* from crop stages (this ground accumulates more or less than the grid credits) and a bias in *days* from observed frost (this ground frosts earlier or later than the region). Nothing is applied silently. A correction appears only once several observations agree, implausible values are set aside rather than averaged in, and the reports behind every figure come back with it. | Not declared |
| goodearth_check_authority_balance | Check this operator's tax balance at the Authority. Returns the sats available for certifying patron credit purchases. When this balance reaches zero, patron top-ups cannot be certified and the operator must call purchase_credits on the Authority. This is the operator's own funding — not a patron balance. Free. | Not declared |
| goodearth_check_balance | Check a patron's credit balance at this operator. This is the patron's spending balance — credits purchased via Lightning for tool calls at this operator. For the operator's own balance at the Authority (needed to certify patron purchases), use authority_check_balance instead. Free — no credits required. Proof of npub ownership is required to prevent anyone-with-the-registry from enumerating balances. | Not declared |
| goodearth_check_payment | Check the payment status of a Lightning invoice. Call after paying the invoice from purchase_credits. Free — no credits required. Proof of npub ownership is required to prevent credit-grant front-running by an observer of the invoice ID. | Not declared |
| goodearth_check_price | Preview the effective cost of a tool call. Shows the base cost and any constraint effects (discounts, free trials, surge pricing). Free — no credits required. | Not declared |
| goodearth_check_proof_status | Check whether a proof grant is still valid. Mirrors ``check_oauth_status`` for the npub-proof flow: a calling agent can ask "will my next paid call accept this dpop_token?" before burning credits on a guaranteed failure. Expiry is read from the grant itself; the only store consulted is the patron's revocation watermark. Free, no side effects — touches no relay. | Not declared |
| goodearth_crop_gdd_status | Where every planting on a block stands, and whether it finishes before frost. Returns, per planting: heat accumulated since set-out against its target, the projected date it reaches that target at the season's recent rate, and a verdict on whether that lands before the median first frost. One call answers the whole block. The season curve and the frost record are shared across plantings, so asking about eight beds costs one round trip rather than eight. | Not declared |
| goodearth_crop_suitability | Which crops finish on this ground, and with how much room to spare. "What can I grow?" is not a lookup. Two farms in the same county, one on a bench and one in a hollow, have different answers — so this measures the block's own frost-free window and the heat it accumulates inside it, then judges each crop's requirement against that. The answer that matters is not yes or no but MARGIN: how much season is left after the crop is done, in the days a grower plans in. A crop that finishes on the last warm day of an average year fails in half of them. Requirements are yours. Published degree-day figures vary by cultivar and maturity group; Good Earth computes against your ground rather than publishing agronomy. | Not declared |
| goodearth_delete_coupon | Delete a coupon. Cascades to all patron redemptions. Any chain step referencing the deleted coupon_id becomes a no-op (the constraint returns neutral on unknown ids) — the Studio surfaces orphan references as warnings. RESTRICTED to operator — requires proof. | Not declared |
| goodearth_delete_operator_credential | Remove a single operator secret field. Deletes one key from the operator's encrypted credential blob without touching the others — the field-level counterpart to ``forget_credentials``, which wipes the whole row. Use it to retire a leftover after an SDK cutover (a Prefect key after Modal, or a stored but untemplated orphan like ``anthropic_api_key``) without taking the operator down for a full re-delivery. Stored-but-untemplated fields are first-class: the delete is keyed on what is vaulted, not on what the current template declares. Idempotent — already-absent fields report ``removed: false`` without rewriting the vault. RESTRICTED to the operator — requires proof (nsec-signed kind-27235 or a cached dpop_token phrase); patron proofs are rejected. A deletion is as destructive as a write. | Not declared |
| goodearth_delete_patron_credential | Remove a single patron credential field. Deletes one field from stored credentials without affecting other fields. Free. Proof of npub ownership is required — this is a write to the patron's sensitive credential vault. | Not declared |
| goodearth_disease_risk | Hours of leaf wetness on this ground, and what the disease models make of them. Returns the estimated wet hours since the season began, every qualifying infection period each model found, which of its criteria were met and which were not, and the wet stretch the forecast implies next. Degree days are the wrong clock for a fungus. What decides an infection is how long the leaf stayed wet and how warm it was while it did, which is why a dry August that accumulated heat all month grows no botrytis. A season with nothing qualifying is reported as exactly that — risk that is absent is as useful to a grower as risk that is present. WETNESS IS ESTIMATED, NEVER MEASURED. No feed publishes a leaf wetness sensor for arbitrary ground, so it is inferred from modelled humidity and rain, and every answer names the estimator and the feed that fed it. That matters more here than elsewhere: humidity crosses the 90% line in a step, and two feeds a couple of degrees apart on dew point can differ threefold on the hours they count. Good Earth runs published models against your ground. It does not publish plant pathology and it never recommends a treatment — registration is jurisdiction-specific and a label rate is law. Take the decision to your extension service, whose word counts where this service's does not. | Not declared |
| goodearth_drying_window | When the dew burns off this ground, the dry days ahead, and the next rain. Answers "is it dry enough yet?" for a grower planning to cut flowers, pick, mow or make hay. Returns this morning's and tomorrow morning's dew-off hour (the first hour the leaves are estimated to stay dry for two hours running), the first run of forecast days with no rain, the next hour of rain, and per day the rain, wet hours, reference evapotranspiration (FAO-56 ET0) and peak vapour-pressure deficit — how hard the air is pulling water out of anything wet. Ten days ahead, from one forecast call. Not wet is not drying: a still, overcast, humid day wets nothing and dries little, which is why ET0 travels with every day. Wetness is ESTIMATED from modelled humidity and rain, never measured, as in `disease_risk`. Conditions only. Good Earth never says a crop is ready to cut or that hay will cure — that depends on the crop, the swath and the field — and it publishes no agronomy. | Not declared |
| goodearth_forget_coupon | Remove a coupon from this patron's redemption list. Cosmetic only — the coupon itself still exists at the operator, and the patron can re-redeem the same code later while the window allows. Free — requires proof of ``npub``. | Not declared |
| goodearth_forget_credentials | Delete vaulted credentials for a specific service and npub. For operator credentials, pass the operator's own npub. For patron credentials, pass the patron's npub. Always requires proof of npub ownership — a deletion is as destructive as a write. | Not declared |
| goodearth_forget_my_ground | Delete every block you have here, and everything recorded on them. Blocks, crops, plantings, pest models, wildlife watches, field reports, tasks, published calendar feeds and the cached weather read for your ground. A real delete, not a retirement: every other removal in this service keeps the row as history, and this one does not, because a grower who asks to be forgotten and is quietly kept has been told something untrue. Any calendar feed you published stops resolving at once. **You remain a patron.** Your balance and your purchase history are not touched — those are the network's ledger rather than this operator's record of your farm, and there is no name, email or KYC in this system to forget. Sign in again with the same npub and you can start over on new ground. Requires proof of the npub, like any call that reads your record. Free: charging someone to leave is a toll on the door out. | Not declared |
| goodearth_frost_window | When frost normally arrives on this ground, and whether it is coming this week. Returns first-frost dates from the last ten seasons, how far the region's own terrain spreads that, and a night-by-night assessment of the coming forecast for the *coldest* ground rather than the average. The spread is the answer's point. Frost forms on still, clear nights when cold air drains off high ground and pools in low, so a single forecast low is optimistic for a hollow and pessimistic for a bench on the same block. | Not declared |
| goodearth_gdd_season_curve | Growing degree day accumulation across a region, season to date. Returns accumulation with its spread across your ground, the band of the last ten seasons to read it against, a 7-day forecast extension, and a projection at the recent rate. The spread is the answer's point: it says how much the same field varies from bench to hollow, which is what decides whether one planting date serves the whole block. | Not declared |
| goodearth_get_nostr_profile | Read an npub's public Nostr profile (NIP-01 kind-0 metadata). Free, no proof — the data is already public on relays. Returns the latest metadata fields (name, display_name, about, picture, banner, nip05, website, lud16) or an empty profile if none is published. | Not declared |
| goodearth_get_notarization_proof | Generate a Merkle inclusion proof that a patron's balance was included in a Bitcoin-notarized snapshot. | Not declared |
| goodearth_get_operator_onboarding_status | Report this operator's configuration readiness. Shows which operator settings are configured, which are missing, and how to deliver each missing value. For patron-level credential status, use get_patron_onboarding_status instead. Free. | Not declared |
| goodearth_get_patron_credential_fields | List stored patron credential field names (not values). Returns the names of fields stored for a patron, plus each field's ``delivered_at`` ISO-8601 timestamp when known (null for secrets vaulted before timestamps were recorded). Values are never exposed — use this to verify which fields are configured and how old each one is. Free. Proof of npub ownership is required: the list of configured fields is itself sensitive (reveals which integrations a patron has set up). | Not declared |
| goodearth_get_patron_onboarding_status | Report a patron's credential readiness for this operator. For set-once services (eXcalibur, TheBrain), shows which patron secrets are configured and which are missing. For dynamic/OAuth2 services (Schwab), reports that no patron credentials are needed. Free. Proof of npub ownership is required because credential presence is sensitive information about the patron's setup. | Not declared |
| goodearth_get_pricing_model | Get the active pricing model for this operator. Free. If no model exists, self-initializes a scaffold with all registered tools at 0 sats. No economic data from code. | Not declared |
| goodearth_list_canonical_identities | Return canonical (tool_id, mcp_name, …) for every tool the wheel exposes. The authoritative source for any client (Studio, agents, FE) that needs to know how this MCP identifies its tools. Reconcile uses this output to UUID-join against the stored pricing model — no name-based UUID derivation, no guessing. Includes both ToolIdentity-seeded tools and any UUID recorded by ``@paid_tool`` that is missing from the registry. The latter appear with ``registered: false`` (and in the top-level ``unregistered`` array) so Reconcile can flag deploy drift instead of silently reporting clean when a live tool was never seeded (#174). If the operator renames a function or rebrands a slug, the mcp_name in this output changes but tool_id stays. That's the whole point of the canonical-UUID design. Also diffs the live FastMCP wire surface against the registry. Tools exposed on the wire but absent from the registry appear in ``unregistered`` so Reconcile can flag deploy drift instead of silently under-reporting (issue #175). Free, no side effects. | Not declared |
| goodearth_list_constraint_types | List all available constraint types and their parameter schemas. Returns the type, category, description, and parameter specs for every constraint that can be used in a pricing pipeline. Free — no credits required. | Not declared |
| goodearth_list_coupons | List every coupon this operator has minted (newest first). Each row carries the current ``times_redeemed`` counter — the Studio renders a progress bar from this against ``total_uses``. RESTRICTED to operator — requires proof. | Not declared |
| goodearth_list_my_coupons | List the coupons this patron has redeemed on this operator. Returns both active and exhausted redemptions with a per-row ``status`` (``active`` / ``window_closed`` / ``patron_limit`` / ``total_limit``). Free — requires proof of ``npub``. | Not declared |
| goodearth_list_notarizations | List recent Bitcoin notarization records. | Not declared |
| goodearth_mint_coupon | Create a new operator-owned discount coupon. | Not declared |
| goodearth_nearby_species | Search what is actually recorded near this ground, a page at a time. This replaces asking for a whole catalogue. There are more than three thousand insect and spider species recorded around one Vermont block; the old answer showed forty of them and said nothing about the rest, and fetching all of them costs eleven round trips to build a list nobody reads. So: search, twenty to a page, and the true total on every page. **Species are a landscape fact, not a field one.** A nine-hectare hayfield contains almost no observations, so the search widens to the surrounding country and the answer says how wide it looked. Every other tool here answers about the drawn ground and nothing outside it; this one cannot. **The count measures observers as much as organisms.** A roadside is better recorded than a back hayfield, so a high count is evidence somebody was standing there — not that a thing is common on your ground. No judgement of any kind. iNaturalist does not say which of these is a pest, a weed, or worth planting, and sorting them into those would be adding a claim the feed never made. | Not declared |
| goodearth_notarize_ledger | Build a Merkle tree of all patron balances and submit the root to Bitcoin via OpenTimestamps. Operator-only background task. Bitcoin confirmation takes 1-6 hours. Free — no credits required. | Not declared |
| goodearth_oracle_about | Describe the DPYC ecosystem via the Oracle. Free. | Not declared |
| goodearth_oracle_get_tax_rate | Get the current DPYC certification tax rate. Free. | Not declared |
| goodearth_oracle_how_to_join | Get DPYC onboarding instructions from the Oracle. Free. | Not declared |
| goodearth_oracle_lookup_member | Look up a DPYC community member by npub. Free. | Not declared |
| goodearth_oracle_network_advisory | Get active network advisories from the Oracle. Free. | Not declared |
| goodearth_pest_catalog | Which pest stages are modelled for this ground this season. Read from the USA-NPN degree-day forecasts rather than from a list in this service, so a model they publish next season appears here without anyone editing anything, and a Georgia orchard gets Georgia's dates. Only layers measured to encode a day of year become dated events. Some carry accumulated heat instead, and one of those reads 281 in Vermont — a convincing 8 October that is really a heat sum. Those are counted and named as unreadable rather than rendered as dates. The insects recorded nearby come from iNaturalist and are a landscape fact: one field holds almost no observations, so the search is widened to the surrounding country and the answer says how far. | Not declared |
| goodearth_pest_threshold | Where a pest model's degree-day stages stand on this ground. Returns, per model: heat accumulated since its biofix, which stages have been crossed, and the projected date of the next one — plus a short list of which pests to go and look for this week. Good Earth computes when your models arrive on your ground. It does not publish entomology: the thresholds are yours, because the authoritative numbers belong to your extension service and vary by region and biotype. | Not declared |
| goodearth_plan_the_season | The season-planning interview, as a workflow to follow. The same text the `plan_the_season` MCP prompt carries. It exists twice because prompt support is uneven: a client that surfaces prompts offers this as a command, and one that does not can still reach it by calling a tool. Both read one constant, so they cannot drift into two different interviews. Follow the returned steps in order, asking one question at a time. The ordering is the point — it moves from the grower's decision to its consequences rather than from the available data to a report. | Not declared |
| goodearth_planting_window | When to start seed, when to put it out, and the last day it still finishes. Heat requirement answers whether a crop CAN finish here. It says nothing about when to start, which is the decision actually made with a seed packet in hand in February. This answers three separate questions: Start seed indoors — counted back from the day it can go out, for a transplanted crop. Out — the earliest the frost record and the soil allow, whichever is later; a tender crop waits for the last spring frost, a hardy one uses the shoulder before it, a direct sowing waits for the soil, which lags the air by weeks. Latest — the last day a sowing still has enough heat left to beat the first fall frost, which is what decides whether an August succession is worth the seed. All from this block's own record rather than a zone map. The requirements are yours. | Not declared |
| goodearth_publish_nostr_profile | Publish a CLIENT-SIGNED kind-0 profile to relays for an npub. The wheel never holds a patron nsec. The frontend signs the kind-0 metadata event with the patron's session key or a NIP-07 extension and passes the signed event (JSON) here; the wheel verifies the signature matches the npub, then relays it to public relays. The signature is the authorization — no proof token, no key custody. Free. | Not declared |
| goodearth_purchase_credits | Buy credits via Bitcoin Lightning. Creates a Lightning invoice. Pay it with any Lightning wallet, then call check_payment to confirm. Proof of npub ownership is required so credits land in the correct ledger. Free — no credits required to call. | Not declared |
| goodearth_receive_credentials | Pick up credentials from the Secure Courier. Completes the CREDENTIAL-DELIVERY flow (the ownership-proof counterpart is ``receive_npub_proof``). **Call this only after the user confirms they have replied.** Deterministic, one-shot retrieval: name the response you want with ``(sender_npub, service, dpop_token)`` and the tool drains ONLY the rendezvous relay that channel was pinned to. Every popped DM with the wrong session phrase is deleted and its sender is NACK'd; the first DM with the matching phrase is accepted (ACK'd) and the scan stops. If none match, the queue is drained and a ``courier_not_found`` result is returned. Do NOT poll, loop, or retry. If a credential_card (ncred1...) is provided, it is redeemed directly without any relay access (dpop_token not required for that path). On success, the payment processor client is reinitialized from the new credentials — no server restart needed. | Not declared |
| goodearth_receive_npub_proof | Receive npub ownership confirmation from a patron. Completes the npub-OWNERSHIP-PROOF flow (the credential-delivery counterpart is ``receive_credentials``). **Call this only after the user confirms they have replied.** Deterministic, one-shot retrieval: name the response with ``(patron_npub, dpop_token)`` — the ``dpop_token`` being the value returned by ``request_npub_proof``. The tool drains ONLY the pinned rendezvous relay that challenge was published on, stopping at the DM whose phrase matches. Mismatched DMs are deleted and NACK'd (without revealing the expected phrase). If called before the user replies, their message will never be found. Do NOT poll, loop, or retry. The signed DM itself proves npub ownership (the patron's nsec signed it). On success, returns a new ``dpop_token``: an Operator-signed **proof grant envelope** ``{"grant": …, "nonce": …}`` bound to the patron, this challenge, and the duration the patron named. The calling application MUST remember that whole string and pass it as ``dpop_token`` on every subsequent paid tool call. The grant is self-verifying; nothing about it is stored here. Free. | Not declared |
| goodearth_redeem_coupon | Claim a coupon by its name (the code the operator shared). Looks up the operator's coupon by ``code``, validates the window and total cap, and records a per-patron redemption row. Subsequent paid tool calls on this MCP auto-apply the discount until ``uses_per_patron`` is exhausted. Free — no credits required. Requires proof of ``npub``. Idempotent: redeeming the same code twice returns the existing redemption. | Not declared |
| goodearth_report_issue | File a field report about this service as a GitHub issue on the operator's repo. Found a tool's metadata or response wrong or confusing? Report it where the tool lives. The **author of record is your npub** — no npub / no proof, no issue — and it is stamped into the issue so the report is attributed to you, not the operator. Costs a small fee (a free write to an issue tracker would be abused). The report is PUBLIC and goes to the maintainers' normal triage; nothing is verified here. Returns the filed issue's repo, number, and url. If this operator has not enabled field reports, returns an "issue reporting not configured" situation and you are not charged. | Not declared |
| goodearth_request_adoption | Ask a chosen Authority to adopt this operator (deferred courtship). RESTRICTED to the operator — requires proof the caller controls this operator's npub. Resolves the Authority's MCP endpoint from the community registry, mints an inline ownership proof with this operator's nsec, and delivers the request MCP-to-MCP. The Authority records it as pending; its owner approves on their own time. Poll ``adoption_status`` for progress; the operator flips to ``ready`` once the Authority provisions it. | Not declared |
| goodearth_request_credential_channel | Open a Secure Courier channel for credential delivery. This is the CREDENTIAL-DELIVERY flow — use it to hand over a service secret (API keys, tokens). To merely prove you control an npub (the usual answer to a ``proof_required`` error), use ``request_npub_proof`` instead. Note: dynamic/OAuth2 services (e.g. Schwab) need NO couriered secret — check ``service_status`` first. Sends a welcome DM with a credential template. The recipient must read the DM in their Nostr client, fill in the fields, and reply manually. **This is a human-in-the-loop flow.** After calling this tool, STOP and tell the user what to do. Wait for the user to confirm they have replied before calling ``receive_credentials``. Do NOT poll or retry — each ``receive_credentials`` call destructively drains the relay mailbox. | Not declared |
| goodearth_request_npub_proof | Request npub ownership proof from a patron via Nostr DM. This is the npub-OWNERSHIP-PROOF flow — use it when a call returns ``proof_required``. It proves the caller controls an npub; it does NOT deliver any service secret. To hand an operator its API keys or OAuth secrets, use ``request_credential_channel`` instead. Sends a challenge DM that the patron must sign and reply to using their Nostr client. **This is a human-in-the-loop flow.** After calling this tool, STOP and tell the user to check their Nostr client and reply to the challenge. Wait for the user to confirm they have replied before calling ``receive_npub_proof``. Do NOT poll or retry — each ``receive_npub_proof`` call destructively drains the relay mailbox. **Returns** a ``dpop_token`` — the one-time challenge nonce shown in the DM. Pass it to ``receive_npub_proof`` to collect the reply. It is a matching token, not a credential: on its own it authorizes nothing. **Lifecycle:** ``receive_npub_proof`` returns the proof grant, which expires after the duration the patron named in their reply. When it expires, call ``request_npub_proof`` again for a fresh challenge, then wait for the user, then call ``receive_npub_proof``. Free. | Not declared |
| goodearth_reset_pricing_model | Erase all pricing models and restore a viable default. Deletes every stored model, then self-initializes a fresh one from the tool registry — all tools at 0 sats with proper UUIDs. Returns the new model. RESTRICTED to operator — requires proof (nsec-signed). | Not declared |
| goodearth_restore_credits | Credit a patron's ledger from a BTCPay-settled invoice. **RESTRICTED to the operator** — the operator owns the books and is the only party who can issue a manual credit grant. Patrons who believe they paid but never got credits must escalate to the operator's support, who then invokes this tool on their behalf. Use cases: cold-start vault races during check_payment, ncred delivery hiccups, patrons closing Top-Off sheets before settle, any infrastructure incident that left an invoice settled at BTCPay but uncredited on the operator's ledger. Idempotent — if the invoice is already credited (in the patron's ``credited_invoices``), returns success with credits_granted=0. | Not declared |
| goodearth_restore_neon_schema | Prepare this operator's database schema again, ignoring the breadcrumb. Diagnostic / recovery tool for when Neon keeps answering 4xx and the operator suspects a table or grant is missing. Every statement is idempotent, so a clean re-run is harmless; the breadcrumb is rewritten at the end. Returns one step per concern, with Neon's own error text inline for any that failed. RESTRICTED to operator — requires proof (nsec-signed). | Not declared |
| goodearth_review_roster | Audit a roster against what this ground's record actually knows. Asked "are these the right pests to watch?", an agent will answer from its own training data — unverifiable, different per model, and confidently wrong exactly at the margins where a review matters. This answers from the record instead: the degree-day models USA-NPN publishes for these coordinates, and what iNaturalist has recorded nearby. Three findings: - **out_of_range** — listed, and this ground's record does not know it. - **absent** — the record knows it well and the roster does not list it. - **implausible** — an observation that cannot be right, with what makes it wrong. This is the one that matters: observations feed ``goodearth_calibration``, which shifts the heat and frost bias for the whole block, so a junk entry degrades every later answer rather than merely showing a wrong row. **Every reason is about the RECORD, never about the animal.** "Not recorded within 16 km" is a fact; "does not live here" is natural history, which Good Earth does not publish. Nothing is removed — the grower who genuinely saw the odd thing is precisely the case worth learning from, so findings are proposed and the patron decides. | Not declared |
| goodearth_service_status | Check the health and configuration of this service. Free. | Not declared |
| goodearth_session_status | Check operator readiness. Returns the operator lifecycle state and clear guidance on what to do next. Free. Lifecycle states: - ready: Vault AND pricing model verified on this call. Proceed with tool calls — this is the answer the moment the vault is up. - warming_up: Persistence could not be reached on this call (a transient failure, seen, not assumed). Retry; the next call completes the bootstrap. Never reported on a clock. - misconfigured: Persistence rejected a query with a permanent SQL error (permission denied, missing relation). Paid tools will fail until the operator repairs the database — retrying does not help. - quota_exceeded: The persistence provider (Neon) answered HTTP 402 — the operator's database has exhausted its compute/storage quota, so the books are locked for billing. Paid tools fail; retrying does NOT help. The operator's Authority must restore capacity (upgrade the plan or wait for the quota reset). Free tools remain available. - not_registered: Operator has no Authority relationship yet. Call register_operator first. - no_identity: Operator nsec is not configured. Deployment issue. | Not declared |
| goodearth_set_pricing_model | Set the active pricing model. RESTRICTED to operator. Requires a valid proof (Schnorr-signed kind-27235 event) proving the caller holds the operator's nsec. | Not declared |
| goodearth_soil_temp_projection | When the soil on this ground crosses a planting threshold. Returns the near-term forecast at planting depth, the date it crosses within that horizon if it does, and when the crossing normally happens here — so a grower knows both "plant this week?" and "how long have I got?". Soil lags air by weeks and is the steadier signal. It is what decides whether a clove or a seed should go in, not one warm afternoon. | Not declared |
| goodearth_task_delete | Remove one task. Scoped to the caller's npub in the WHERE clause, so a known id is not on its own enough to delete somebody else's task. | Not declared |
| goodearth_task_list | One page of a region's tasks, ordered and filtered by the database. The sorting, the timeframe filter and the search all happen in SQL, so a long list costs one page rather than the whole table. ``sort_col`` names a column rather than supplying one: it indexes a fixed map and falls back to the due date, so an unrecognised value gives the default order rather than an error — and can never reach the query. | Not declared |
| goodearth_task_save | Create or update one task. Single-day by design: one date and optional clock times on it. No recurrence and no multi-day spans — a farm list is a list of days. | Not declared |
| goodearth_task_set_done | Mark one task done, or put it back. | Not declared |
| goodearth_tree_suitability | Whether a tree survives and gets its chill on this ground. A tree is not asked "does it finish before frost" — that is a question only something that must finish in one season can be asked. It is asked two others, both settled before it goes in the ground: * **Will it survive?** Every winter on record has a coldest night; a cultivar has a limit. The answer is how often the first went below the second. * **Will it fruit?** A deciduous fruit tree needs chill hours to break dormancy cleanly. The answer is how many winters on record delivered them. Both come back as a FREQUENCY across the record rather than a yes. A tree that survives nine winters in ten is a different proposition from one that survives five, and any single word hides the difference. Chill is counted as hours in the 32-45 °F band between 1 November and 15 February — the window the published chill-hour figures were derived against. A wider window would bank more hours against a requirement calibrated to a narrower one and report a tree comfortable where it is not. The requirements are yours. Hardiness limits and chill hours are cultivar figures that vary widely within a species; Good Earth computes what this ground delivered against them and does not publish agronomy. | Not declared |
| goodearth_tree_year | When spring reached this ground, and what the sap did. **First leaf and first bloom**, from USA-NPN's Spring Index, dated for this block and set against its own thirty-year normal. "Spring is early this year" is a headline; "leaf-out reached this block seven days before its normal" is something to act on. First bloom is also when the pollen starts. That is a restatement of what bloom is, not a pollen forecast — Good Earth has no pollen feed, models none, and says nothing about what anyone should do about it. **The sap run**, for a block with maple, birch or walnut on it. Sap moves on freeze and thaw rather than on warmth: a night below freezing followed by a day above it. Counted off this ground's own season record, so it costs no extra call. A block with nothing tappable gets no sap section — the count would be just as true there and would answer a question nobody on that ground asked. The trees are read from the block's own record; nothing needs passing. | Not declared |
| goodearth_update_coupon | Patch a coupon's editable fields. Pass only the fields you want to change. To set a cap to unlimited (NULL in the schema), pass ``clear_uses_per_patron=true`` or ``clear_total_uses=true``. Renaming the code is allowed — existing patron redemption rows survive (they key on coupon id). RESTRICTED to operator — requires proof. | Not declared |
| goodearth_update_operator_credential | Add or update a single operator secret field. Merges into the operator's stored credentials without touching the others — the field-level counterpart to re-delivering the whole bundle over Secure Courier. Use it to rotate one secret (a reissued ``btcpay_api_key``, say) without restating the six you did not change, where any field omitted from a courier reply is destroyed. The value is never echoed back. RESTRICTED to the operator — requires proof (nsec-signed kind-27235 or a cached dpop_token phrase); patron proofs are rejected. | Not declared |
| goodearth_update_patron_credential | Add or update a single patron credential field. Merges into existing stored credentials without affecting other fields. Useful for setting an account identifier after OAuth, changing a default brain, etc. Free. Proof of npub ownership is required — this is a write to the patron's sensitive credential vault. | Not declared |
| goodearth_wildlife_calendar | When the other creatures working your season arrive. A farm is not only its crops. Robins arrive, woodchucks wake, squirrels start caching. The same drivers that time a crop time the animals — heat accumulation, day length, and the calendar the sun keeps — so they can be computed for your ground rather than read off a regional average. Three clocks, because animals do not all run on one: a degree-day threshold, a photoperiod threshold (migration runs on this, which is why it barely moves between a warm year and a cold one), or a date from your own record. The thresholds are yours. Good Earth works out when they arrive here; it does not publish natural history. | Not declared |
| goodearth_wildlife_catalog | Which animals are actually recorded around this ground. Birds, mammals, amphibians and reptiles observed near here, ranked by how often each has been seen — so the answer for a Vermont lakeshore is not the answer for a Georgia orchard, and neither is a roster someone typed. Species are a landscape fact. A nine-hectare field contains almost no observations of anything, so the search widens to the surrounding country and the response reports how wide it looked; treating that footprint as the farm would be the dishonest version. The ranking measures observers as much as animals — a roadside is better recorded than a back field — so the counts travel with the answer. Pass a scientific name as `species` and this answers with that animal's life-cycle phenophases instead — nest building, nestlings, fledged young, calls or song, emergence above ground. Those come from USA-NPN, which publishes them; they are not written into this service. Roughly half the species recorded around a farm have them, and one that does not returns an empty list rather than a guess, because "not tracked" and "does nothing" are different claims. Set `with_events` to get those phenophases for EVERY species in the list at once, as `habit_events`. Ask for it before writing a roster: an agent left to name events from memory writes "rut onset" and "southbound flights", words this service has never used, where NPN says "Nest building" and "Fledged young". It costs one upstream call per species, which is why it is off by default. **The event name is not load-bearing.** A wildlife row is dated by its DRIVER — heat, daylight, an interval, a calendar date — and the label is the grower's own words. `habit_events` is a courtesy to a caller looking for the right word, never a list of the only acceptable ones: "Big Night crossing" is a real thing a salamander does and no catalogue holds it. Good Earth times an event you set. It does not publish natural history. | Not declared |
