Flexai Rate Limits

FlexAI Token Factory enforces per-API-key request rate limits, tiered by account status (free vs. paid), plus a prepaid account budget. Exceeding the rate limit returns 429 with a Retry-After header; exhausting the account budget returns 402 Payment Required.

Flexai Rate Limits is the machine-readable rate-limit profile for FlexAI on the APIs.io network, in the API Commons Rate Limits shape.

It captures 3 rate-limit definitions, measuring requests_per_minute.

Limit state is signalled in the limit, remaining, reset, and retryAfter response headers, and an exhausted limit returns HTTP 429.

The profile also includes response codes documented for throttled and paymentRequired.

Tagged areas include Rate Limiting and Inference.
