## 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-facilitator-picker-facpick-cf9446dd
```

Example prompt: Run the x402 facpick diagnostic on openclawproductions.com so I can confirm my OpenX402 payment flow is working — go ahead and pay the $0.04 USDC fee and show me what the paid JSON response looks like.

## When to prefer this

Choose this endpoint when you need to test or validate x402 micropayment flows using a real paid API call via OpenX402 as the facilitator. It is purpose-built for diagnostics — not for production data retrieval. Prefer it over other x402 test endpoints when you specifically need to verify EIP-3009 authorization handling or OpenX402 facilitator selection behavior.

## Known failure modes

- HTTP 402 returned when no valid EIP-3009 payment authorization is included — response body contains payment challenge with extras
- Invalid or expired EIP-3009 token causes payment rejection
- OpenX402 facilitator unavailable causes request failure
- Malformed properties parameter may result in unexpected response
- Network timeout if OpenX402 facilitator settlement is slow

## 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 name ('facpick'), a human-readable title ('Fac Pick'), the price ('$0.04'), and a diagnostic note confirming the paid response shape. Returns HTTP 402 with EIP-3009 payment details if the request is unpaid.
