## 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-cpi-source-diagnostic-endpoint-0af14940
```

Example prompt: Run the x402 cpisrc diagnostic against the OpenX402 facilitator — pay the $0.04 USDC fee and show me what the paid JSON response contains.

## When to prefer this

Use this endpoint when you need to test or validate the x402 micropayment protocol flow end-to-end, specifically with the OpenX402 facilitator and a $0.04 USDC charge. It is best suited for developers and agents debugging x402 HTTP 402 responses, eip3009 payment metadata, or verifying that a paid SKU resolves correctly after settlement. Not intended for production data retrieval.

## Known failure modes

- HTTP 402 returned when payment is missing or invalid — includes eip3009 extras describing required payment
- Payment facilitator mismatch — only OpenX402 is accepted; other facilitators will be rejected
- Malformed properties query parameter may result in unexpected response or error
- Network timeout or unavailability of openclawproductions.com host
- Invalid or expired USDC payment authorization rejected by facilitator

## 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 ('cpisrc'), a human-readable title ('CPI Source'), the price ('$0.04'), and a diagnostic note. Unpaid requests return HTTP 402 with eip3009 payment extras instead.
