Is this your server? Own a server? ToolFit hosted watch re-checks it every 24 h ($0.25 per 30 days) or 6 h ($0.60) and sends you an HMAC-signed webhook when its tools or grade change: POST https://api.youraitools.co/toolfit/v1/watch. To opt out, see About & opt-out.
Tools: lookup_site get_pricing get_docs get_service_status
lookup_site | 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). params: url* |
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. params: none |
get_docs | The whole machine guide as JSON: quickstart, what each verdict means, packs, the rules every check runs, and every public route. params: none |
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. params: none |
Entries describe changes in tool definitions. They are not statements about a server, its quality or its author. The grade measures how the tool definitions fit model providers (token cost, schema compatibility, confusable names) as scored by the ToolFit engine at the time of the listing. JSON: append .json. Opt-out: how or hello@youraitools.co.
