  REPLACES the 2026-05-04 bulk-sweep scaffold, which carried invented per-tier numbers
  (10/100/1000 rpm, 1k/100k monthly quotas) that Contify has never published. Those values
  were fabricated defaults and have been removed. Contify publishes NO rate-limit numbers,
  no window, no burst ceiling, no response headers and no exhaustion status code. The only
  public statement is that limits are configurable per subscription tier. An honest zero is
  data; a plausible invented limit is not.

description: >-
  Rate-limit record for the Contify Business News API. Contify advertises tier-scaled,
  configurable rate limits but publishes no numeric limit, window, burst ceiling or
  runtime signalling header on any public page; the API reference is behind the
  developer.contify.com login.

    No RateLimit-* , X-RateLimit-* or Retry-After header was present on the live
    unauthenticated responses observed against https://api.contify.com/v4.1/updates
    (HTTP 403) and .../updates?format=api (HTTP 406) on 2026-09-05. An authenticated
    response could still carry them; that could not be observed without a key.
responseCodes:
  throttled: null
  quotaExceeded: null
  note: The status code returned on exhaustion is not documented.
