## 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 legalfournier-com-x402-payment-test-b8d6e2c9
```

Example prompt: Run a real $1 USDC test payment on Base mainnet using x402 and give me back the onchain receipt so I can confirm it settled.

## When to prefer this

Use this endpoint when you need to verify that x402 HTTP payment infrastructure works end-to-end with a real $1 USDC settlement on Base mainnet. It is ideal for integration testing, agent payment capability demos, or confirming that a wallet and x402 client are correctly configured before going live. Prefer this over mock or testnet endpoints when you need real onchain proof.

## Known failure modes

- Insufficient USDC balance in wallet — payment cannot be settled
- Invalid or missing x402 payment header — 402 Payment Required returned
- Network congestion on Base causing delayed confirmation
- Wallet not configured for Base mainnet — wrong chain error
- Payment amount mismatch — endpoint expects exactly $1 USDC

## How this service works

Settle a real $1 USDC payment on Base mainnet and return an onchain receipt.

## Output

An onchain receipt confirming that a real $1 USDC payment was settled on Base mainnet, including transaction details such as a transaction hash or block confirmation data.
