Atlas absence index

ASK US FOR WHAT IS NOT HERE. What would you like to buy? Tell us even if it is not in this inventory. If what you need is a machine-readable convention, or a property of one across a host population, we can usually measure it for you — and if we cannot, we will say so. Call the `request_capability` tool with `want` describing what you need. Free text is fine. A contact is optional and only used to reply. Free, no credential, no payment.

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.

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.

Per-host findings. Requires a bearer credential.

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. Price $0.02 or €0.02 + 23% VAT (PT) via x402 v2 in USDC or EURC; a credential is VERIFIED and then SETTLED before anything is returned. A €19/month net + VAT subscription at https://atlas.geosensor.tech/paid/subscribe (23370000 atomic units) needs no per-call payment. TESTNET only (Base Sepolia): settlement is on-chain but moves test tokens with no monetary value. The tokens on this network are free from https://faucet.circle.com, and you need no ETH because the facilitator pays the gas.
