status: historical
note: >-
  DERIVED from the artifacts harvested 2026-08-03 while the API was live. The docs host
  is now a parked domain (see lifecycle/gleefulai-lifecycle.yml), so nothing here could
  be re-verified against live documentation on this pass and nothing was upgraded to
  `searched`.
authentication:
  style: none
  keys: false
  model: >-
    Keyless. Access is metered per call and settled with x402 micropayments — an
    unauthenticated request to a priced endpoint answers HTTP 402 with a base64 x402 v2
    challenge in a Payment-Required header, and the caller settles USDC on Base
    (eip155:8453) to proceed. The OpenAPI declares no components.securitySchemes at all.

idempotency:
  supported: false
  header: null
  evidence: >-
    No idempotency key header, parameter or documentation exists anywhere in the
    harvested surface — zero case-insensitive matches for "idempoten" across the
    OpenAPI, the llms.txt and the machine-readable pricing document. All 14 priced
    operations are non-idempotent POSTs that charge on each call, so a retry after a
    timeout is a second payment. NO `Idempotency` pointer is emitted for this provider.
pagination:
  supported: false
  style: null
  evidence: >-
    No cursor, page, offset or limit parameter is declared on any of the 36 operations.
    Every response is a single audit/extraction result, so there is no collection
    surface to paginate.
request_shape:
  http_methods: [GET, POST]
  content_type: application/json
  discoverability_convention: >-
    A distinctive and genuinely useful convention: every priced POST path also answers
    GET with a free "help" operation returning the request/response shape for that path
    (operationIds suffixed `_help`, 14 of them). GET /api/examples/{endpoint} returns a
    sample request and response for any endpoint. An agent could therefore learn the
    full input contract without paying and without an API key.
  request_schemas_declared: false
  request_schemas_note: >-
    The published OpenAPI declares no requestBody schemas and components.schemas is
    empty, so the machine-readable contract carries no input shape — the shapes were
    only reachable through the live GET help/examples endpoints, which no longer answer.
response_shape:
  media_type: application/json
  schemas_declared: false
  note: components.schemas is empty; no 200 response schema is declared on any operation.
error_envelope:
  format: not-rfc9457
  documented_statuses: [200, 402]
  note: >-
    402 is the only non-2xx status documented across the entire API. See
    errors/gleefulai-problem-types.yml.
request_tracing:
  request_id_header: null
  evidence: No request-id or correlation header is documented.
rate_limit_signaling:
  headers: []
  status_on_exhaustion: null
  evidence: >-
    No X-RateLimit-*, RateLimit-*, or Retry-After header is documented and no 429
    response is declared. See rate-limits/gleefulai-rate-limits.yml.
