Troubleshooting

429 is a rate limit response. Lower your concurrency, retry with backoff, or switch to a plan with a larger quota.

Common causes

• Too many concurrent requests
• Quota of the current plan exhausted
• Retrying immediately without backoff

How to fix

• Limit concurrency and retry with exponential backoff
• Switch to a plan with a larger quota
• Cache repeated requests
