What you saw
429, which most SDKs treat as retryable and back off from on their own.
Why it happened
The gateway caps each user at 200 requests per minute. The cap is there mostly to keep runaway loops from melting the proxy. Your agent crossed it inside a 60-second window.How to fix it
- Add a small delay or exponential backoff on retry. Most SDKs handle this automatically when they see a
429. - If parallel workers are hitting the gateway, throttle them so they share the budget.
- On Cloud, the 200 requests/minute cap is fixed. Lean on the backoff in step 1. Self-hosted, raise it with
MANIFEST_RATE_MAX_REQUESTSin your.envand restart. See Environment variables.
