## 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-211-diagnostic-endpoint-f3465dc3
```

Example prompt: Run the wwwmatch211 x402 diagnostic and show me what the paid JSON response looks like — I want to confirm the eip3009 payment flow works end-to-end with OpenX402.

## When to prefer this

Use this endpoint specifically when you need to test or validate the x402 micropayment protocol flow using the OpenX402 facilitator, or when you need to inspect what a $0.02 USDC-gated diagnostic payload looks like for the wwwmatch211 SKU. It is not a general-purpose data API but rather a protocol diagnostic tool.

## Known failure modes

- HTTP 402 with eip3009 extras if payment is missing or invalid
- Facilitator rejection if not using OpenX402 as the facilitator
- Malformed properties input may yield unexpected results
- Network timeout if the openclawproductions.com host is unavailable

## 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 identifier ('wwwmatch211'), a descriptive note, the price ('$0.02'), and the human-readable title ('Www Match 211'). Without valid x402 payment, returns HTTP 402 with eip3009 payment requirement extras instead.
