name: cloro API rate and concurrency limits
published: true
limit_count: 2
note: 'Quotes copied from the markdown twins (<page>.md) of the docs pages on 2026-10-07. Two limit types: a fixed per-endpoint per-key rate limit on every /v1/* path, and plan-based concurrency slots shared by sync monitor requests and async tasks. No 429 sends Retry-After. limits[] holds the rows quoted from the source page (https://cloro.dev/docs/guides/concurrency); other_documented_limits holds limits quoted from the pricing page, the async guide and the error-handling guide, each with its own source URL - split so every limit_text is verifiable on the one page named in source.'
limits:
- name: Per-endpoint rate limit
  limit_text: 1,000 requests per second per endpoint
  limit: 1000
  window: second
  scope: per API key, per endpoint (each /v1/* path has its own independent 1,000 RPS bucket)
  endpoint: /v1/*
  error_code: RATE_LIMIT_EXCEEDED
  source: https://cloro.dev/docs/guides/concurrency
- name: Free tier concurrency
  limit_text: 1 concurrent request
  limit: 1
  scope: per organization (concurrent sync requests + processing async tasks)
