Capabilities

Tools 4

get_docs

The whole machine guide as JSON: quickstart, what each verdict means, packs, the rules every check runs, and every public route.

Discovered
get_pricing

Every product for sale — the check (one payment, one check) and the catalog snapshot — with its price, the query parameters the paid request needs, and the exact x402 v2 payment requirements. Call this before buying.

Discovered
get_service_status

Whether the service is selling right now, in which mode and on which network, and if not, why not. This is configuration, not liveness: the health endpoint is at /health.

Discovered
lookup_site

Free. The last dated verdict for a website, if it was ever checked and listed: verdict, score and its band, date, badge, profile URL, every public finding with the agent skill (aiskills402.com) that fixes it, and the URL to buy a fresh check. An unknown site is a normal answer (known: false), not an error.
