## 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-gdp-source-diagnostics-7ad65759
```

Example prompt: Can you call the x402 gdpsrc diagnostic endpoint and show me what the paid JSON response looks like — I want to confirm my OpenX402 facilitator and EIP-3009 payment flow are working correctly?

## When to prefer this

Use this endpoint when you need to test or validate an x402 HTTP payment integration, specifically with the OpenX402 facilitator and EIP-3009 authorization. It is ideal for developers verifying their micropayment client handles the 402 response and payment flow correctly before building against live data endpoints.

## Known failure modes

- HTTP 402 returned with EIP-3009 extras if no valid payment is included
- Invalid or missing properties parameter may return an error
- OpenX402 facilitator unavailable may block payment processing
- Malformed EIP-3009 authorization results in payment rejection

## 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 identifier ('gdpsrc'), a diagnostic note clarifying this is an example paid shape, the price ('$0.04'), and the title ('GDP Source'). Returned only after a valid x402 micropayment is processed through the OpenX402 facilitator.
