## 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-201-diagnostic-9b0b90ef
```

Example prompt: Run the wwwmatch201 x402 diagnostic so I can confirm the EIP-3009 payment challenge and paid JSON response shape are working correctly through the OpenX402 facilitator.

## When to prefer this

Choose this endpoint when you need to test or demonstrate x402 micropayment gating behavior — specifically the HTTP 402 challenge/response cycle with EIP-3009 extras via the OpenX402 facilitator. It is a diagnostic tool, not a production data service, so prefer it for integration testing, agent payment flow validation, or debugging x402 payment infrastructure rather than fetching real business data.

## Known failure modes

- HTTP 402 returned when no valid x402 payment header is included — includes EIP-3009 payment challenge extras
- Payment rejected by OpenX402 facilitator if wrong facilitator or token is used
- Malformed properties parameter may result in 400 error
- Endpoint may be unavailable if openclawproductions.com is down

## How this service works

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

## Output

On successful payment: a JSON object with fields 'sku' (wwwmatch201), 'note' (diagnostic message), 'price' ($0.02), and 'title' (Www Match 201). Without valid payment: HTTP 402 status with EIP-3009 payment challenge extras specifying how to pay via USDC through the OpenX402 facilitator.
