note: Replaces a 2026-05-04 bulk-sweep scaffold whose tier names (free/professional/enterprise) and numbers (10
  rpm, 1,000/month) were invented. The values below are Cvent’s published usage tiers.

description: Published Cvent REST API usage tiers, per-second throttling, burst ceilings, response headers and 429
  semantics.
headers:
  limit: X-RateLimit-Limit
  remaining: X-RateLimit-Remaining
  reset: X-RateLimit-Reset
  note: Cvent documents these three response headers on every response. It does NOT document Retry-After or the
    RFC 9238 RateLimit-* family.
responseCodes:
  throttled: 429
  quotaExceeded: 429
  disambiguation: '429 is overloaded: message "Too Many Requests" = per-second throttle (retry with backoff); message
    "Limit Exceeded" = daily quota exhausted (do not retry until after the reset). The two are only separable by
    reading the body message — Cvent’s own SDK retry overlay excludes 429 from automatic retry for exactly this
    reason.'
introspection:
  usage: GET /ea/usage
  tier: GET /ea/usage/tier
  note: The API exposes its own consumption and tier, so an agent can check quota before spending it.
