Kairos Signal — verifiable DePIN data API

By kairossignalAll Kairossignal servers

DePIN network telemetry, 370+ networks with live data. Every value carries an upstream verify URL.

First seen 2 Oct 2026. One server, whatever directories list it: each directory listing keeps its own page and history.

ToolDescriptionBehaviour
check_balanceCheck your remaining credit balance. Use after purchases to see remaining credits.Not declared
fetch_datasetQuery records from a dataset with limit/offset. Free tier: 10 records per query. For depin_onchain, raw archived observations, including rejected rows, are retained. observation_quality reports limited PKT airdrop checks; not_checked means not validated. This read-time annotation is not covered by original proof hashes.Not declared
get_data_dictionaryONBOARDING SPEC: freshness, history depth, coverage and endpoints per feed (depin_onchain, depin_daily, health_profiles, signal_ledger, market_ticks, zk_footprints). Machine-legible; answers 'how stale is this and how far back does it go' for every feed. Free, no key.Not declared
get_derivation_ledgerDERIVATION TRUTH: raw upstream payloads, SHA-256-pinned, with the exact collector code hash for each fetch. Replay any published value: fetch the verify_url yourself, run the pinned code, compare. Answers 'a hash proves a footprint, not the derivation' — divergence from origin is mechanically detectable. Free.Not declared
get_statsGet aggregate statistics from the databasesNot declared
list_datasetsList the current dataset catalog with record counts. Browsing is free; existing query and daily-call limits apply.Not declared
list_productsBrowse purchasable products with prices in credits ($1 = 1 credit). DePIN supply-telemetry, provenance, derivation-replay, history and the intel bundle start at $0.49. Grade purchases are conditional on measured-grade availability; check /v1/credits/pricing before buying. Signal-feed tiers, DAG-manifold tiers and mcp_unlimited are priced but NOT yet purchasable: their entitlement is not wired into the serving API, so purchase_data refuses them with 503 not_yet_deliverable rather than charging you for nothing. Call after register_agent.Not declared
purchase_dataBuy a product with your credits; the data ships inline in the response. Deliverability is product-specific, including grade availability; check /v1/credits/pricing before buying — call list_products for the live prices rather than trusting a figure restated here, which is how a price in a second place drifts from the first. The signal_*, dag_* and mcp_unlimited keys are priced but return 503 not_yet_deliverable — they are deliberately blocked, not broken, because nothing grants their entitlement yet. Credits buy DATA; they do not change your access tier. Use api_key from register_agent.Not declared
register_agentSTART HERE. One call: get an API key instantly (no card, no human, no Stripe, ~5 seconds) plus $5 free credits, no card (first 3 keys per IP per 30 days). Past that per-IP limit a key is still created, at $0, and the response says so — it is never a silent zero. Works immediately: query live DePIN telemetry (501 symbols, every value carries a verify_url you can check yourself), GPU inference, DAG manifold. Try get_data_dictionary first if you want the coverage spec, or GET https://kairossignal.com/try with zero setup. Nothing to cancel; credits just sit there until you spend them. Then list_products to see what $0.49+ buys.Not declared
topup_creditsAdd credits. Card (one call): {"method": "stripe", "amount": N} where N is $20 or $99 — returns a Stripe checkout_url already bound to your api_key, and credits post automatically once Stripe confirms payment at $1 = 1 credit. No human step and no wallet needed. USDC on Base ({"method": "usdc"}) is also accepted but requires more work: verify your sender first via POST /v1/credits/crypto/challenge and /verify with X-API-Key, sign the returned challenge with your own EOA, then pass the verified from_address and send only after a successful quote — credit requires finalized Base evidence. Instructions: https://kairossignal.com/docs/crypto.htmlNot declared
verify_footprintRetained Merkle-membership check for one depin_onchain observation: stamp_day (YYYYMMDD), leaf_index (0-based row in /attestations/batch_<day>.tsv), expected_row_sha256. verified=true ONLY when the row at that index hashes to expected_row_sha256 AND its inclusion path reaches that day's manifest merkle_root. Says nothing about Bitcoin status or upstream accuracy. Other datasets: unsupported (no retained proof).Not declared
