Re-read against the live docs page 2026-08-13 and confirmed absent. An agent that hits the limit gets a 429 with a JSON error body and no machine-readable remaining budget or reset time, so pacing must be entirely client-side. This is the single biggest runtime-signal gap on the surface. status_on_exhaustion: 429 enforcement: per API key, rolling one-second window (not per IP) errorBody: '{"error":{"code":429,"message":"Too Many Requests","description":"The call-rate limit has been reached.

Reduce request frequency and implement exponential backoff with jitter. - code: 403 message: Insufficient funds description: Returned when the account has insufficient API credits to complete the request. No credits are charged on this error. recommendations: - Implement exponential backoff with jitter when receiving 429 responses. - Use client-side throttling to proactively manage request rates. - Avoid immediate retries after a rate limit error. - For async endpoints (e.g., /backlinks/export), both the task creation request and status polling requests count toward the RPS limit. - Check remaining credits via /account/subscription (free, 0 credits consumed) before executing large workflows. customLimits: description: Higher throughput and custom rate limits are available for both the Data API and Project API upon request.
