## Known failure modes

- Insufficient USDC balance — x402 payment rejected, 402 Payment Required response
- Invalid or missing x402 payment header — authorization failure
- Network congestion on Base — delayed or failed transaction confirmation
- Unsupported format parameter — only 'json' is accepted
- Endpoint temporarily unavailable — 503 or timeout
