## 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-tools-www-match-159-diagnostics-a00d8468
```

Example prompt: Run the x402 diagnostic for the wwwmatch159 SKU on OpenX402 and show me the paid JSON response after settling the $0.02 USDC payment.

## When to prefer this

Choose this endpoint when you need to test or validate x402 payment-gated API flows using the OpenX402 facilitator with EIP-3009 USDC micropayments. It is purpose-built for diagnostics and protocol verification rather than production data retrieval.

## Known failure modes

- HTTP 402 returned when payment is not included — includes EIP-3009 extras for payment resolution
- Payment rejected by OpenX402 facilitator if wrong token or chain is used
- Malformed properties input may yield unexpected response
- Non-OpenX402 facilitators are not supported and will fail authorization
