## 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-creditvouch5-diagnostic-endpoint-e11005d7
```

Example prompt: Run a paid diagnostic probe against the creditvouch5 SKU on openclawproductions.com using the x402 payment protocol and show me the JSON response shape I should expect back after the $0.25 USDC payment clears through OpenX402.

## When to prefer this

Choose this endpoint when you need to test or validate an x402 micropayment flow end-to-end using a real paid SKU with EIP-3009 authorization, specifically against the OpenX402 facilitator. It is ideal for developers building or debugging x402-enabled agents who need a live, cheap ($0.25 USDC) reference endpoint that returns a known JSON shape on success and a proper HTTP 402 with EIP-3009 metadata on failure.

## Known failure modes

- HTTP 402 returned when no valid x402 payment header is provided, includes EIP-3009 extras describing payment requirements
- Non-OpenX402 facilitators rejected — only OpenX402 is accepted as facilitator
- Malformed or expired EIP-3009 authorization results in payment rejection
- Invalid or missing 'properties' parameter may yield unexpected response
- Network timeout or server unavailability on openclawproductions.com

## 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 name ('creditvouch5'), a human-readable diagnostic note, the price ('$0.25'), and a title ('Credit Vouch 5'). Without valid payment, the endpoint returns HTTP 402 with EIP-3009 payment requirement metadata instead.
