## 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-wwwmatch190-diagnostic-endpoint-c6c63ec5
```

Example prompt: Run the x402 diagnostic probe for SKU wwwmatch190 on OpenX402 and show me the paid JSON response including the SKU, title, and price fields.

## When to prefer this

Use this endpoint when you specifically need to test or validate x402 HTTP payment protocol flows, EIP-3009 payment extras, or OpenX402 facilitator behavior on a fixed-price diagnostic SKU. It is not a production data service — choose it when your goal is protocol-level diagnostics, not real-world data retrieval.

## Known failure modes

- HTTP 402 returned with EIP-3009 extras when no valid x402 payment header is present
- Payment rejected by OpenX402 facilitator if wrong facilitator is used
- Malformed 'properties' query parameter may result in unexpected behavior
- Network timeout or 5xx if the diagnostic service 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 ('wwwmatch190'), a human-readable title ('Www Match 190'), the price ('$0.02'), and a diagnostic note confirming the paid response shape. If payment is not provided, returns HTTP 402 with EIP-3009 payment extras indicating how to pay via the OpenX402 facilitator.
