## Known failure modes

- Payment amount below $0.10 minimum — rejected with validation error
- Payment amount above $1000 maximum — rejected with validation error
- x402 payment failure or USDC transfer rejected — credits not added
- Invalid or missing payment header — 402 Payment Required response
- Network or gateway timeout — uncertain whether credits were added
