limit_count: 0
limits: []
summary: >-
  The provider publishes no per-client rate limit and imposes none. Every path is a static file on
  an edge cache; no request is rejected for frequency. This is a documented zero, not an
  undocumented gap.

    No X-RateLimit-*, no RateLimit-*, no Retry-After on a 200. Probed live rather than assumed.
exhaustion:
  status_code: null
  detail: >-
    The API defines no exhaustion response. The provider names the only real ceiling honestly in
    /.well-known/api-onboarding: the host's platform account allows 100,000 requests a day across
    the whole site, and beyond that the platform, not the API, refuses.
fair_use_guidance:
  stated: true
  url: https://www.pathwren.workers.dev/.well-known/api-onboarding
  detail: >-
    "Please fetch /data/agents.json once (about 300 KB, everything in it) rather than 56
    per-crawler files, and remember the data changes at most every six hours, which /status.json
    tells you exactly."
conditional_requests:
  etag: true
  if_none_match: true
  returns_304: true
  last_modified: false
  if_modified_since: ignored
  detail: >-
    Stated verbatim in api-onboarding: "Every response carries an ETag and honours If-None-Match
    with a 304. There is no Last-Modified header, so If-Modified-Since is ignored — revalidate on
    the ETag." Consistent with the live headers observed above.
