## 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 openclaw-x402-quote-book-diagnostic-c5c8cc89
```

Example prompt: Pull the quotebook diagnostic from the OpenClaw x402 endpoint — I want to confirm the paid JSON response comes back correctly with the right SKU and price after settling 0.22 USDC through OpenX402.

## When to prefer this

Choose this endpoint when you need to test or demonstrate the x402 HTTP payment protocol with eip3009 authorization using a real paid SKU endpoint backed by the OpenX402 facilitator. It is specifically useful for diagnosing x402 payment flows, verifying correct HTTP 402 response structure, and confirming that a USDC micropayment of $0.22 successfully unlocks a gated API response.

## Known failure modes

- HTTP 402 returned when no valid x402 payment header is provided, with eip3009 extras indicating required payment details
- Payment authorization rejected if eip3009 token is malformed or expired
- Facilitator mismatch error if a facilitator other than OpenX402 is used
- Network timeout if the endpoint is unreachable
- Invalid properties parameter format may result in unexpected response shape

## 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 ('quotebook'), a human-readable title ('Quote Book'), the price ('$0.22'), and a diagnostic note clarifying this is an example paid shape and not a live settlement. Unpaid requests receive HTTP 402 with eip3009 payment extras.
