## 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-seat-gap-diagnostics-d9ae29a6
```

Example prompt: Run the x402 seatgap diagnostic for me — I want to confirm my eip3009 payment authorization and x402 client are working correctly by making a real $0.03 USDC paid call.

## When to prefer this

Choose this endpoint when you need to test or validate an x402 HTTP payment flow end-to-end using a live, low-cost ($0.03 USDC) diagnostic call. It is specifically designed for developers and agents verifying their eip3009 authorization, x402 client configuration, or OpenX402 facilitator setup — not for production data retrieval.

## Known failure modes

- HTTP 402 returned when payment authorization is missing or invalid, with eip3009 extras in the response body
- Facilitator mismatch if a non-OpenX402 facilitator is used, causing payment rejection
- Malformed eip3009 authorization header leading to payment verification failure
- Network timeout if the endpoint is unavailable
- Incorrect properties parameter schema causing a 400 bad request

## 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 ('seatgap'), a diagnostic note clarifying this is a paid example response, the price ('$0.03'), and a human-readable title ('Seat Gap'). Unpaid or improperly authorized requests return HTTP 402 with eip3009 payment details.
