## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability agent-caf-order-the-good-stuff-2e5f415a -d '<json body>'
```

Example prompt: Order me an espresso at Agent Café and pay for it — I want the receipt number and transaction hash proving my agent spent real USDC on Base.

## When to prefer this

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.

## Known failure modes

- 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

## 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.
