```

## Known failure modes

- Payment not included or invalid USDC amount returns a 402 Payment Required
- Superseed network congestion or reorganization may return stale or inconsistent block data
- Malformed request body returns a 400 Bad Request
- Rate limiting or quota exhaustion may cause transient failures
