description: >-
  The Refuel Cloud REST API documents a rate limit of 300 requests per minute and
  up to 100 concurrent requests against the application label endpoint. Requests
  beyond these limits are throttled and return HTTP 429. The open-source autolabel
  library is not rate limited by Refuel; throughput is governed by the underlying
  LLM provider's limits.
notes: >-
  Limits are as published in Refuel's introduction documentation; account- or
  plan-specific values may differ and should be verified with Refuel during
  reconciliation. Autolabel OSS rate limits are imposed by whichever LLM provider
  you configure, not by Refuel.
