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.
