Rate limits

REST — rate limits and headers.

Per-API-key rate limits. Limits vary by tier and endpoint.

Headers

  • X-RateLimit-Limit — limit for the window

  • X-RateLimit-Remaining — remaining

  • X-RateLimit-Reset — when the window resets

  • Retry-After (on 429) — seconds to wait

The SDK handles 429 + Retry-After automatically. For direct REST calls, check Retry-After and back off.
