description: >-
  Documo applies per-endpoint rate limits on its REST API. The fax history and
  reports endpoints are documented as limited to 8 calls per minute; exceeding
  the limit returns an HTTP 429 response, and no further requests are served
  until the one-minute window resets. Limits on other endpoints (send, numbers,
  webhooks, account) are not fully documented and are not reconciled here.
notes: >-
  Only the fax history / reports limit (8 calls per minute) is publicly
  documented. Confirm limits for send-fax, numbers, webhooks, and account
  endpoints, plus any account-level or per-plan throughput caps, against
  Documo documentation during reconciliation. Marked reconciled false.
