## 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-health-paid-skew-diagnostic-64b7fcaf
```

Example prompt: Run the x402 health paid skew diagnostic against openclawproductions.com using a GET request and tell me what the paid JSON response looks like after payment clears.

## When to prefer this

Use this endpoint when you need to test or validate the x402 paid micropayment flow specifically for the OpenX402 facilitator — particularly to confirm that EIP-3009 payment metadata is correctly returned on unpaid requests and that a settled payment yields the expected diagnostic JSON. Prefer this over generic health checks when the goal is verifying x402 protocol compliance rather than general API uptime.

## Known failure modes

- HTTP 402 returned when no valid payment is included — contains EIP-3009 extras describing payment requirements
- OpenX402 facilitator unavailable — payment cannot be settled, request hangs or times out
- Invalid HTTP method — only GET, HEAD, and DELETE are accepted; other methods return an error
- Origin URL misconfigured — defaults to openclawproductions.com if not specified, may cause unexpected routing

## 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 ('healthpaidskew'), a human-readable title ('Health Paid Skew'), the price ('$0.02'), and a diagnostic note confirming this is a live paid response shape. Unpaid requests return HTTP 402 with EIP-3009 payment requirement metadata instead.
