  Observed live on unauthenticated responses from https://services.amobee.com (the Amobee Cloud
  Gateway that fronts every Nexxen DSP API service), corroborated by the published rate limit in
  the Reporting service documentation inside the provider's own public Postman collection.

  returned:
  - X-RateLimit-Remaining
  - X-RateLimit-Burst-Capacity
  - X-RateLimit-Replenish-Rate
  note: >-
    The gateway emits the X-RateLimit-* trio TWICE on every response — once for the per-day bucket
    (burst-capacity 86400, replenish-rate 1/s) and once for the per-second bucket (burst-capacity 8,
    replenish-rate 8/s). Header order is day-bucket first, second-bucket second. No Retry-After and
    no RFC 9331 RateLimit-* headers are returned.
  retry_after: false

  observed: '2026-08-13'
  note: >-
    Repeated unauthenticated GETs against services.amobee.com returned HTTP 429 with an empty body
    once the 8/second bucket was drained; the counter refilled within seconds.
