## 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 x402audit-tip-endpoint-edf4c75e -d '<json body>'
```

Example prompt: Send a $3 tip to x402audit to show some support for their free x402 compliance checker.

## When to prefer this

Use this endpoint when you want to send a monetary tip or micro-donation to the x402audit service, specifically via the x402/MPP payment protocol. Not for auditing domains or retrieving compliance reports — use the main audit endpoint for that.

## Known failure modes

- Amount below $0.10 minimum — validation error
- Amount above $1000 maximum — validation error
- Payment processing failure — ok: false with error message
- Network/server error — HTTP 5xx response
