## 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-180-diagnostic-endpoint-67072eed
```

Example prompt: Run the x402 wwwmatch180 diagnostic so I can see what a successfully paid response looks like — I want to confirm the EIP-3009 payment flow is working with OpenX402 as the facilitator.

## When to prefer this

Choose this endpoint when you need to test or demonstrate x402 HTTP payment-gating behavior end-to-end with EIP-3009 authorization, specifically using the OpenX402 facilitator. It is best suited for developers debugging micropayment flows, validating payment credential setups, or exploring what a real paid x402 JSON response looks like at minimal cost ($0.02 USDC). Not suitable for production data retrieval or non-x402 use cases.

## Known failure modes

- HTTP 402 returned with EIP-3009 extras when no valid payment header is supplied
- Invalid or expired EIP-3009 authorization results in payment rejection
- Facilitator mismatch: only OpenX402 is accepted; other facilitators will be rejected
- Malformed properties parameter may result in unexpected behavior or error
- Network timeout if OpenX402 facilitator settlement is delayed

## How this service works

Paid x402 diagnostics. Unpaid paid-SKU requests return HTTP 402 with eip3009 extras. Facilitator: OpenX402 only.

## Output

Returns a JSON object containing the SKU name ('wwwmatch180'), a descriptive note, the price ($0.02), and the title ('Www Match 180'). If no valid x402 payment is provided, the endpoint returns HTTP 402 with EIP-3009 payment extras indicating how to pay via OpenX402 facilitator.
