## 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-wwwmatch231-paid-diagnostic-endpoint-997e19d5
```

Example prompt: Run the wwwmatch231 x402 diagnostic — I want to test my payment client by hitting that $0.02 USDC paid endpoint and see what JSON shape comes back after settlement through OpenX402.

## When to prefer this

Choose this endpoint when you need to test or validate an x402 payment client implementation, specifically against a live paid SKU that uses the OpenX402 facilitator and eip3009 payment authorization. It is ideal for integration testing, protocol compliance checks, and debugging HTTP 402 flows with micropayments in USDC. Not suitable for any production data retrieval or non-diagnostic purposes.

## Known failure modes

- HTTP 402 returned if no valid x402 payment header is included — includes eip3009 extras describing payment requirements
- Payment rejected if a facilitator other than OpenX402 is used
- Malformed or missing 'properties' input parameter may cause unexpected behavior
- USDC balance insufficient on the paying address leads to failed settlement
- Network or blockchain congestion may delay payment confirmation

## 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 ('wwwmatch231'), a diagnostic note, the price ($0.02), and the title ('Www Match 231'). Unpaid requests return HTTP 402 with eip3009 payment extras including the payment requirements for OpenX402 facilitator settlement.
