Technical details
Endpoint
POSThttps://api.402.coffee/test/scam/startWhen to prefer
Use this endpoint when you specifically want to test the x402 micropayment protocol end-to-end on Base with real USDC, and need back a structured receipt with a transaction hash. It is purpose-built for agents exercising live on-chain payment flows in a controlled test scenario, not for production purchases or other blockchains.
Side effects
- Insufficient USDC balance — payment rejected, no receipt issued
- x402 payment header missing or malformed — 402 Payment Required response
- Network congestion on Base causing delayed transaction confirmation
- Invalid or expired payment nonce — transaction rejected
- Endpoint returns error if x402 facilitator cannot verify the payment
