## 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-fed-source-diagnostics-endpoint-a826c437
```

Example prompt: Run the fedsrc diagnostic on the x402-tools endpoint so I can confirm my payment client correctly handles the 402 challenge, settles via OpenX402, and gets back the paid JSON payload.

## When to prefer this

Choose this endpoint when you need a real, live HTTP 402-gated endpoint to test or demonstrate x402 micropayment flows, specifically using the OpenX402 facilitator and eip3009 authorization. It is ideal for integration testing, debugging 402 challenge/response cycles, or validating that an agent or client correctly handles paid API access before deploying against production endpoints.

## Known failure modes

- HTTP 402 returned if payment is not submitted or fails eip3009 validation
- Facilitator mismatch: only OpenX402 is accepted; other facilitators will be rejected
- Malformed properties parameter may result in unexpected response shape
- Network timeout or unavailability of openclawproductions.com host

## 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 diagnostic payload with fields: sku ('fedsrc'), note (example paid JSON shape disclaimer), price ('$0.04'), and title ('Fed Source'). Unpaid requests receive HTTP 402 with eip3009 payment challenge extras instead.
