description: >-
  Cronitor enforces rate limits on both the Management (REST) API and the
  Telemetry API. The Telemetry API limits requests to 5 per second per endpoint
  with bursts up to 10, and 50 per second per IP with bursts up to 250. The
  Management API returns 429 responses when limits are exceeded; specific
  thresholds for the Management API are not publicly disclosed. The Business
  plan advertises unlimited API requests.
