Refuel Ai Rate Limits

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.

It captures 2 rate-limit definitions, measuring requests and concurrent_requests.
