## 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 openclaw-x402-api-disallow-diagnostics-80806b79
```

Example prompt: Run the x402 apidisallow diagnostic probe against openclawproductions.com using a GET request so I can confirm the paid SKU response shape and EIP-3009 payment gating is working correctly.

## When to prefer this

Use this endpoint specifically when you need to test, diagnose, or validate x402 HTTP 402 payment-gating behavior with EIP-3009 extras via the OpenX402 facilitator. It is purpose-built for protocol diagnostics rather than delivering real application data. Prefer this over general HTTP testing tools when you need to confirm x402 micropayment flows work end-to-end with USDC on a live endpoint.

## Known failure modes

- HTTP 402 returned when payment header is missing or invalid — includes EIP-3009 extras indicating required payment
- Invalid method (non-GET/HEAD/DELETE) may result in rejection
- Malformed origin URL query parameter may cause unexpected behavior
- OpenX402 facilitator unavailability may block payment settlement

## 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 ('apidisallow'), a human-readable title ('API Disallow'), the price ('$0.02'), and a diagnostic note confirming the paid response shape. Unpaid requests return HTTP 402 with EIP-3009 payment requirement metadata instead.
