## 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-149-diagnostics-endpoint-02afb6b6
```

Example prompt: Run a diagnostic probe on the wwwmatch149 SKU endpoint at openclawproductions.com — I want to verify the x402 payment gate is working correctly and see the paid JSON response after settling the $0.02 USDC fee through OpenX402.

## When to prefer this

Choose this endpoint when you need to test, validate, or demonstrate the x402 HTTP micropayment protocol with EIP-3009 payment flows using the OpenX402 facilitator. It is purpose-built for diagnostics and integration testing of USDC-gated APIs, not for production data retrieval. Prefer it over generic REST endpoints when your goal is to verify 402 paywall behavior, inspect paid response shapes, or confirm facilitator compatibility.

## Known failure modes

- HTTP 402 returned when no valid x402 payment token is provided, with EIP-3009 payment details in response extras
- Invalid or expired payment token causes 402 re-challenge
- Non-OpenX402 facilitators are rejected (only OpenX402 is supported)
- Malformed 'properties' query parameter may result in unexpected or empty response
- Network or server errors returning 5xx if the diagnostic endpoint is unavailable

## How this service works

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

## Output

A JSON object containing the SKU identifier ('wwwmatch149'), a diagnostic note confirming the paid response shape, the price ('$0.02'), and a human-readable title ('Www Match 149'). Unpaid requests return HTTP 402 with EIP-3009 payment instruction extras instead.
