Technical details
Endpoint
GEThttps://nine.x420.dev/api/puff?utm_source=zero.xyzWhen to prefer

Side effects
- Insufficient USDC balance to cover the $1 payment — payment rejected
- x402 payment protocol error — facilitator or payment channel issue
- Token swap fails on-chain — swap transaction hash may be null
- Network congestion causes transaction timeout
- Invalid or missing wallet/payment credentials
