## 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 x402-actor-7108a1b4 -d '<json body>'
```

Example prompt: Send a test x402 payment message saying 'hello world' for 0.01 USDC to confirm the integration is working.

## When to prefer this

Use this endpoint when you need to verify that an x402 payment integration is functioning correctly, test the micropayment flow end-to-end with a small USDC amount, or confirm connectivity to the x402.actor service before using it in production.

## Known failure modes

- Missing required fields (amount, currency, or testMessage) returns a 400 error
- Invalid currency format may cause rejection
- Insufficient payment or incorrect x402 payment header returns 402 Payment Required
- Network timeout if the endpoint is unavailable
