description: >-
  OpenStatus Cloud governs usage primarily through per-plan resource limits
  rather than published per-second REST throttles. The dominant constraints are
  the number of monitors, the minimum check frequency (periodicity), the number
  of status pages and components, the available regions, and data retention,
  all of which scale by subscription tier. The on-demand /check endpoint is
  intended for ad-hoc use and is subject to fair-use limits. Self-hosted
  deployments under AGPL-3.0 are bounded only by the operator's own
  infrastructure.
notes: >-
  OpenStatus does not publish fixed numeric per-minute REST API rate limits;
  effective throughput is governed by plan resource limits. Confirm any
  request-rate ceilings and Retry-After behavior during reconciliation.
