}9 tools, verified live
list_toolsread-onlyThe APIs the compendium covers: each with the hosts its trials hit, trust tier, version count, and counts of verified claims and spec divergences.
list_versionsread-onlyThe spec versions recorded for one API, newest first, each fingerprinted by its spec hash. The ids identify versions for get_version_diff.
get_tool_knowledgeread-onlyEvery verified claim about an API as structured records (latest version by default): paginated, filterable by kind, spec divergences flagged, each with compact evidence (trial id, probe, status, request line). verbose=true adds response previews.
get_divergencesread-onlyWhere the live API contradicts its own OpenAPI spec: documented limits not enforced, types not validated, required parameters not required, enums accepting other values. Compact evidence; verbose=true adds response previews.
search_claimsread-onlyFull-text search over verified claims by host and symptom, e.g. "github per_page 500", "npm search size 0", "is latitude required on /v1/forecast": the lookup for an unexpected 4xx/5xx, a parameter that seems ignored, an odd page, or wrong filter results. Optionally restricted to one API (name, host or URL). Compact evidence unless verbose=true.
get_tool_docsread-onlyThe verified behavior sheet for an API: Markdown built only from verified claims, with spec contradictions first, then sibling differences, undocumented rules, and per-endpoint behavior (error shapes, pagination, validation, auth), every line citing trial ids. Accepts a tool name, a host, or the full URL about to be called; a URL or path scopes the sheet to that endpoint plus a one-line index of t
get_version_diffread-onlyWhat changed in verified behavior between two spec versions of an API (changed, added and removed claims), as opposed to what changed in the spec text.
request_targetQueues a public, read-only, credential-free API for probing, from a target object { name, spec_url (OpenAPI 3 document), category?, include_paths?, baseline? (valid values for required params per path), optional_values?, server? }. The spec is fetched and parsed and the battery planned immediately; probing runs rules-only on the worker's next pass. Requires a per-user key; quota 3 requests per key
get_request_statusread-onlyStatus of a target request (pending, running, done or failed), with the run id and summary once processed.
