Rate limits and concurrency
Credits and rate limits are independent. HTTP 429 costs zero credits.
Defaults#
Unauthenticated IP: 180/min · API key: 60/min · user: 90/min · user concurrency: 5 · body: 256 KB · results: 50.
Headers#
429 includes Retry-After, RateLimit-Limit, RateLimit-Remaining, and RateLimit-Reset.
Safe retry#
Use exponential backoff for 429 and retryable 5xx. Automatically retry only idempotent requests.
