What is this error?
A 429 'Rate Limit Exceeded' error from H2O.ai means you've sent too many requests in a given time period. This is a protective measure to ensure fair usage across all users. It can be triggered by your individual usage or by H2O.ai-wide capacity constraints.

- Exceeded your plan's requests-per-minute (RPM) or tokens-per-minute (TPM) limit
- Organization or project-level quota exhausted for the billing period
- Too many concurrent/parallel requests from the same API key
- H2O.ai is throttling all users due to high global demand
- Free tier limits reached — upgrade required for higher throughput
✓ How to Fix It
- Check your usage dashboard on H2O.ai's platform to see current consumption
- Implement exponential backoff: wait 1s after first 429, then 2s, 4s, 8s
- Reduce concurrency — send fewer parallel requests
- Use batching or queuing to spread requests over time
- Consider upgrading your plan for higher rate limits
- If available, use H2O.ai's batch/async API for non-urgent requests
