Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-170-diagnostic-endpoint-1aa6e5fd
```

Example prompt: Run the wwwmatch170 x402 diagnostic probe on OpenX402 and show me the paid JSON response — I want to confirm the EIP-3009 payment flow and the returned SKU shape are working correctly.

## When to prefer this

Choose this endpoint when you need to test or validate the x402 HTTP payment protocol flow end-to-end using a real $0.02 USDC microtransaction, specifically with the OpenX402 facilitator and EIP-3009 authorization. It is ideal for developers building or debugging x402-gated APIs who want a low-cost, concrete probe with a defined response schema rather than a mock or sandbox environment.

## Known failure modes

- HTTP 402 returned if payment header is missing or invalid — includes EIP-3009 extras with payment instructions
- Incorrect facilitator (non-OpenX402) results in payment rejection
- Malformed properties parameter may yield unexpected or empty response
- Network timeout if OpenX402 facilitator is unreachable
- Payment authorization expired or nonce reused causes rejection

## 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 ('wwwmatch170'), a human-readable title ('Www Match 170'), the price ('$0.02'), and a diagnostic note confirming the paid response shape. Unpaid requests receive HTTP 402 with EIP-3009 payment instructions instead.
