Tools
| Tool | Description | Behaviour |
|---|---|---|
| absence_rate | Measured absence rate for a population, with the evaluated denominator and sample provenance. Pass `gap_class` (e.g. PH-C019) for one class; omit it for the whole table. Aggregate only: no per-host findings. | Not declared |
| adoption_curve | Dated adoption series: share of sites whose robots.txt takes a stance on AI agents, by Common Crawl epoch, single vantage. Called with no arguments it returns the trend and the caveats, not the whole table. Pass `epoch` for one point, `series: true` for all of them, or `withheld: true` for the undersampled epochs that are kept out of the series. Caveats are always included — read them before quoting a number. | Not declared |
| bulk_export | Per-class numerators with Wilson intervals and the discarded-as-unknown share, Kaplan-Meier survival of directive adoption by cohort, directive lineage, declaration growth, and RFC 9728 auth-discovery conformance detail — none of it on the free surface — with an ed25519 attestation naming the chain head it was derived from. FREE SAMPLE, no credential: https://atlas.geosensor.tech/free/sample (names every section and shows two numerator cells in full). Price $0.02 or €0.02 via x402 v2, payable in USDC or EURC (scheme `exact`, network `eip155:84532`) — the `accepts` array carries both and the client chooses; EURC is a euro e-money token, so a euro payment reaches an EU bank with no FX step. needs a bearer credential AND a payment that is VERIFIED and then SETTLED before anything is returned. TESTNET only (Base Sepolia): settlement is on-chain but moves test tokens with no monetary value. OR SUBSCRIBE: €19/month for 2,000 calls. AN AGENT CAN BUY ONE ITSELF at https://atlas.geosensor.tech/paid/subscribe — x402 v2, 19000000 atomic units of USDC or EURC, and the response returns the key in its body and in the x-subscription-key header. Present that key in the x-subscription-key header afterwards and no per-call payment is needed. A human can be invoiced in euros instead, with no crypto at all. PAYING COSTS YOU NOTHING: the tokens on this network are free from https://faucet.circle.com, and you need no ETH because the facilitator pays the gas. No third party has completed a payment yet; doing so is how you tell us this is worth having. | Not declared |
| host_report | Per-host findings. Requires a bearer credential. | Not declared |
| request_capability | ASK US FOR WHAT IS NOT HERE. What would you like to buy? Tell us even if it is not in this inventory. This service is a measurement harness, not a fixed catalogue: if what you need is a machine-readable convention or a property of one across a host population, we can usually add it to the probe set and measure it for you — and if we cannot, we will say so plainly. Call the `request_capability` tool with `want` describing what you need. Free text is fine. A contact is optional and only used to reply. This tool is free, needs no credential and no payment. It is the one call we most want you to make. | Not declared |
