Measured conclusion: Alive, not deep-tested. L2 outcome: not_attempted.

Verified, reproduced behavior of public HTTP APIs: spec gaps, errors, pagination, auth.

Measured tools (9)

• list_tools read-only

  The APIs the compendium covers: each with the hosts its trials hit, trust tier, version count, and counts of verified claims and spec divergences.

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• list_versions read-only

  The spec versions recorded for one API, newest first, each fingerprinted by its spec hash. The ids identify versions for get_version_diff.

  Parameters:

  • tool (required) — string — tool name (e.g. github-rest), or the host / URL you are about to call (e.g. api.github.com)

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• get_tool_knowledge read-only

  Every 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.

  Parameters:

  • tool (required) — string — tool name (e.g. github-rest), or the host / URL you are about to call (e.g. api.github.com)
  • kind — string — required | type | auth | pagination | error_behavior | response_shape | undocumented_constraint | undocumented | other
  • limit — integer — default 100
  • offset — integer
  • verbose — boolean
  • version — integer — tool_version id; default latest

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• get_divergences read-only

  Where 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.

  Parameters:

  • tool (required) — string — tool name (e.g. github-rest), or the host / URL you are about to call (e.g. api.github.com)
  • verbose — boolean
  • version — integer

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• search_claims read-only

  Full-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.

  Parameters:

  • query (required) — string
  • tool — string — tool name (e.g. github-rest), or the host / URL you are about to call (e.g. api.github.com)
  • limit — integer
  • verbose — boolean

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• get_tool_docs read-only

  The 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 the others. Brief by default (what would change the request); full=true adds per-parameter validation, response shapes and all evidence ids.

  Parameters:

  • tool (required) — string — tool name (e.g. github-rest), or the host / URL you are about to call (e.g. api.github.com)
  • full — boolean — the whole sheet: per-parameter validation, response shapes, all evidence ids
  • path — string — request path to scope to one endpoint, e.g. /repos/github/rest-api-description/issues; template segments match anything
  • brief — boolean — deprecated: the default; brief=false is the same as full=true
  • version — integer

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• get_version_diff read-only

  What 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.

  Parameters:

  • tool (required) — string — tool name (e.g. github-rest), or the host / URL you are about to call (e.g. api.github.com)
  • from_version (required) — integer
  • to_version (required) — integer

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• request_target

  Queues 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 per day. Returns a request id for get_request_status.

  Parameters:

  • target (required) — object — the target definition; see targets/*.json in the repo for examples

  Hints: read-only no · destructive no · idempotent no · open-world no

• get_request_status read-only

  Status of a target request (pending, running, done or failed), with the run id and summary once processed.

  Parameters:

  • request_id (required) — integer

  Hints: read-only yes · destructive no · idempotent yes · open-world no
