description: >-
  Published Cvent Platform REST API rate limits. The three usage tiers, their daily quota,
  per-second rate and burst are stated verbatim in the "Rate Limits" section of the official
  OpenAPI's info.description; the response headers, the 429 semantics and the quota-inspection
  endpoints come from the Handling Rate Limits guide on the developer portal. Replaces the
  2026-05-04 scaffold, whose numbers were placeholders.
headers:
  limit: X-RateLimit-Limit
  remaining: X-RateLimit-Remaining
  reset: X-RateLimit-Reset
  retryAfter: null
  policy: null
  note: >-
    Documented example response headers are X-RateLimit-Limit, X-RateLimit-Remaining and
    X-RateLimit-Reset (a unix timestamp). Cvent does not document a Retry-After header or the
    RFC 9238 RateLimit-* family; its own retries overlay tells SDK consumers to use fixed
    exponential backoff instead of reading a server-supplied delay.
responseCodes:
  throttled: 429
  quotaExceeded: 429
  note: >-
    Both conditions return 429. Cvent's own overlay comment states they are only distinguishable
    by the message body — "Too Many Requests" is per-second throttling and safe to retry, while
    "Limit Exceeded" means the daily quota is gone and retrying burns quota. For this reason
    Cvent deliberately EXCLUDES 429 from the default SDK retry status codes (502/503/504 only).

policies:
  - name: Failed requests still count
    description: >-
      Every request counts against the quota, including requests that themselves return 429.
      Stated explicitly in the Handling Rate Limits guide.
  - name: Backoff strategy
    description: >-
      Cvent's published SDK retry policy: exponential backoff, initial interval 2s, max interval
      16s, exponent 2.0, max elapsed 40s (~5 attempts), then log and stop. Connection errors are
      retried; 429 is not retried automatically.
  - name: Quota reset
    description: Daily quota resets at 12 midnight GMT (+0). Rate is a 1-second window.
  - name: Limits may change
    description: >-
      "Please note that these limits may change as the Cvent API Platform evolves." — official
      OpenAPI info.description.
