## 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-dual-host-wk-diagnostics-1ef3de87
```

Example prompt: Run the Dual Host WK x402 diagnostic on openclawproductions.com and confirm the payment goes through — I want to verify my OpenX402 facilitator integration is working and see the paid JSON response.

## When to prefer this

Use this endpoint specifically when you need to test or validate an x402 micropayment flow using EIP-3009 authorization through the OpenX402 facilitator. It is ideal for developers building x402-compatible clients who want a real, low-cost ($0.02 USDC) paid endpoint to probe against, rather than mocking responses.

## Known failure modes

- HTTP 402 returned when no valid EIP-3009 payment authorization is included
- Payment rejected if facilitator is not OpenX402
- Malformed payment header results in 402 with eip3009 error details
- Invalid or missing properties parameter may cause unexpected behavior
- Network errors from openclawproductions.com infrastructure

## 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 ('dualhostwk'), a diagnostic note, the price ('$0.02'), and the title ('Dual Host WK'). If payment is not provided or invalid, returns HTTP 402 with EIP-3009 payment requirement extras instead.
