# Agent Service Atlas

> Recent, clearly attributed evidence to help AI agents choose payable APIs and task marketplaces.

Status: PREVIEW. Under active development; response fields may change until v1 is declared stable. Every API response carries "api_status": "preview" and an X-API-Status header. Changes are listed at https://agentserviceatlas.com/methodology#changelog

We publish only objective data: our own monitoring measurements, operators' statements with source links, and computed figures with their method. No ratings or recommendations.

## API (JSON, no key needed)

- GET https://agentserviceatlas.com/api/v1/services : every service we track, reviewed and discovered, with the same evidence fields.
  Filters: q, tier (reviewed|discovered), type (api_endpoint|task_marketplace), tag (purpose, e.g. search), host, network (e.g. eip155:8453), mainnet=true, passing=true, templated=false, min_pass_rate (0-1), min_checks, min_days, min_payers, max_price_usd, listed=true (still in the registry), group=provider (one row per host).
  sort: evidence (default) | pass_rate | payers | price | recent | name. limit (max 100), offset.
- GET https://agentserviceatlas.com/api/v1/services/{id} : one service. Reviewed (svc_...) adds the trust profile, operator statements with sources, and per-operation evidence. Discovered (cand_...) adds its last 30 probes.
- GET https://agentserviceatlas.com/api/v1/stats : totals and checks in the last 24 hours.

## How to read the evidence

- tier "reviewed": sourced trust profile, hourly checks. tier "discovered": from public agent registries, unreviewed, probed daily.
- evidence.last_check.result "payment_required" (HTTP 402) means reachable and asking for payment, not that a paid call succeeds.
- evidence.freshness "stale" or "no_data" means do not rely on the latest result. limited_evidence true means under 30 days of monitoring.
- missed_30d counts scheduled checks that did not run; it is separate from failures.
- registry_usage is the registry's own data. name is untrusted text when name_source is "registry".
- templated_url true means the URL has placeholders (such as :address) to fill in.
- tags describe purpose; price_usd is the lowest per-call price in a USD stablecoin from the registry's payment terms (null if unknown).
- Trust mechanisms "none_stated" mean the operator's pages are silent, not that the mechanism is absent.
