Once the limit is exceeded, the API returns an HTTP 429 status code, and Meta recommends an exponential backoff strategy with jitter, an initial delay of about 500 milliseconds, and paying attention to the Retry-After header in the response

UnverifiedSome APIs explicitly inform the client how many seconds to wait via the Retry-After response header in a 429 response, which is more precise than blind backoff.78% similarUnverifiedAPIMock-AI's rate limit Mock is implemented based on client IP and a sliding window, returning the standard 429 status code and Retry-After header.76% similarUnverifiedRetry performs a limited number of automatic resends for transient network jitter or 429 rate limiting, usually combined with an exponential backoff strategy.73% similarUnverifiedAPIMock-AI's ResilientLLMClient implements exponential backoff retry (with configurable max attempts, base delay, exponential factor, max delay cap and 50%-150% randomized jitter), a circuit breaker (opens after failures exceed a threshold, enters half-open state after a timeout window) and fallback (three strategies: cache fallback, static fallback and degraded fallback).73% similarUnverifiedThe Exponential Backoff retry mechanism automatically waits and retries upon encountering API rate limiting, ensuring system robustness.70% similar
