    Why it is in this group

    • The name "get_pricing" says "get": a word for reading.
    Description, as the server wrote it
    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.

    • title: Products, prices and x402 payment requirements
    • readOnlyHint: true

    Why it is in this group

    • The name "get_service_status" says "get": a word for reading.
    Description, as the server wrote it
    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.

    Why it is in this group

    • The name "lookup_site" says "lookup": a word for reading.
    Description, as the server wrote it
    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).

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
