## 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-retail-source-diagnostics-endpoint-ed326fef
```

Example prompt: Can you call the x402 retail source diagnostic endpoint and show me the paid JSON payload it returns after settling the $0.04 USDC micropayment through OpenX402?

## When to prefer this

Choose this endpoint when you need to test, demonstrate, or debug the x402 HTTP payment protocol flow using the OpenX402 facilitator, specifically for the retailsrc diagnostic SKU. Prefer this over generic REST endpoints when validating EIP-3009 micropayment authorization and 402-gated API behavior end-to-end.

## Known failure modes

- HTTP 402 returned with EIP-3009 extras if payment is not included or facilitator not recognized
- Non-OpenX402 facilitators are rejected — only OpenX402 is accepted
- Malformed properties parameter may result in unexpected or empty responses
- Network or endpoint unavailability returns standard HTTP error codes

## 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 ('retailsrc'), a diagnostic note clarifying this is an example paid shape, the price ('$0.04'), and a human-readable title ('Retail Source'). This confirms a successful payment-gated API transaction via the x402 protocol.
