Tools

• get_docs ~70 tokens
  The whole machine guide as JSON: quickstart, what each verdict means, packs, the rules every check runs, and every public route.
• get_pricing ~96 tokens
  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.
• get_service_status ~84 tokens
  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.
• lookup_site ~134 tokens
  Free. The last dated verdict for a website, if it was ever checked and listed: verdict, score, date and badge. An unknown site is a normal answer (known: false), not an error. To get a fresh check, buy one (see get_pricing).
