## Known failure modes

- Insufficient USDC balance causes payment failure and 402 response
- Malformed x402 payment header results in authentication rejection
- Empty or malformed input properties cause model to return empty data array
- Model unavailability from underlying DeepSeek provider returns error code
- Network timeout from vergex.trade backend infrastructure
- Invalid wallet address in payment header causes transaction failure
