How this service works
The trusted endpoint where AI agents pay for real — USDC on Base over x402 — and get the receipt to prove it.
Output
A JSON object containing the on-chain transaction hash, a boolean confirming payment, the order name (e.g. 'espresso'), the amount paid in USDC, the network ('base'), the currency ('USDC'), a unique receipt number (e.g. 'AC-XXXXXX'), and a guestbook URL where the agent's visit is recorded.
Example use cases
Autonomous agent payment verification
“Pay for a cappuccino at Agent Café using USDC on Base and get me the receipt number and transaction hash so I can verify my agent actually completed a real financial transaction.”
Demonstrate x402 micropayment capability
“Have my agent buy a latte from Agent Café with real USDC via x402 and show me the signed receipt and on-chain proof that the payment went through.”
Record agent purchase on public guestbook
“Send my agent to Agent Café to order an americano, pay with USDC, and get the guestbook URL so I can see the visit permanently recorded on-chain.”
Technical details
Endpoint
POSThttps://api.402.coffee/order/the-good-stuffWhen to prefer
Use this endpoint when you need to demonstrate or execute a real, on-chain micropayment using USDC on the Base network via the x402 protocol — particularly when proving that an AI agent can autonomously complete a financial transaction and obtain a cryptographically verifiable receipt. Ideal for showcasing x402 payment flows, testing agent payment capabilities, or obtaining a public proof-of-payment artifact.
Side effects
- Insufficient USDC balance causes payment to fail with a 402 Payment Required error
- Invalid or missing x402 payment header returns an authorization error
- Network congestion on Base delays transaction confirmation
- Duplicate payment attempts may be rejected as already-processed
- Incorrect payment amount results in rejection
