  99designs DOCUMENTS no rate limits — the complete API reference (Getting started,
  Authorization, Briefs, Designers, Coupons, Products, Orders) was read in full on
  2026-08-13 and contains no quota, throttle, burst, retry or 429 guidance. The limit
  below was OBSERVED on live unauthenticated responses: every response from
  api.99designs.com carries X-RateLimit-Limit / X-RateLimit-Remaining /
  X-RateLimit-Reset, with a limit of 100 and a reset timestamp that lands on the next
  whole minute. Repeated probing confirmed the counter decrements per request and
  resets to 100 at the minute boundary, i.e. a 100-request-per-minute window. The
  status code returned on exhaustion is not stated in the docs and was not induced
  (deliberately not tested against a production host), so it is recorded as unknown.
limits:
- scope: per-client
  window: 60s
  limit: 100
  burst: null
  applies_to: all api.99designs.com responses observed, authenticated or not
  method: probed
  note: >-
    Window is aligned to the wall-clock minute (X-RateLimit-Reset is the epoch seconds
    of the next minute boundary), not a rolling window from first request.
