The rate-limits page states that limits are "customized", that "distinct rate limits are applied to different API endpoints", and that they are "enforced on an account-by-account basis" — without naming a single quota, window or burst value. No rate-limit response headers are documented anywhere in the developer docs, and none of the six published OpenAPI contracts declares a 429 response or a RateLimit/X-RateLimit/Retry-After header. An agent therefore cannot read its remaining budget at runtime; it can only observe the 429 and back off. limit_count is 0 because zero numeric limits are published, not because limits are absent.' scope: per-account and per-endpoint exhaustion: status_code: 429 documented: true retry_after_header: not documented guidance: 'The docs recommend integrations monitor for 429 status codes and employ a retry mechanism with a gradually increasing delay strategy.' response_headers: documented: [] observed_in_spec: [] note: 'No X-RateLimit-*, RateLimit-* or Retry-After header is documented or declared in any published contract. Live observation was not possible: every MyCarrier API operation requires credentials, so no unauthenticated response could be inspected.' limits: [] gaps: - No published numeric quota, window or burst for any endpoint. - No documented rate-limit response headers, so remaining budget is not machine-readable. - 429 is documented in prose but is not declared as a response in any OpenAPI contract.
