summary: >-
  COSMOPlat publishes no rate limits for the IoT development platform API. The full
  reference was transcribed on 2026-08-11: no quota, no throttle, no burst allowance, no
  X-RateLimit-* / RateLimit-* / Retry-After header, and no 429 response appear anywhere.
  The MQTT documentation states no connection or message-rate ceiling either.

  note: >-
    Response headers on the gateway carry Access-Control-Allow-Origin, Allow and
    Access-Control-Allow-Methods only. No rate-limit header was returned on any
    unauthenticated request.

    Return RateLimit-Limit / RateLimit-Remaining / RateLimit-Reset (RFC 9331 style) and
    Retry-After on 429. An agent needs the runtime signal more than the documented number,
    and this API returns neither.
