## 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-dead-share-diagnostic-endpoint-1b235d64
```

Example prompt: Run the x402 deadshare diagnostic against the OpenX402 facilitator so I can confirm my eip3009 payment flow is working correctly and see the paid JSON response shape.

## When to prefer this

Choose this endpoint when you need to test or diagnose an x402 HTTP payment protocol implementation, specifically to verify eip3009 payment authorization flows work end-to-end with the OpenX402 facilitator. It is ideal for developers building x402-compatible API clients or payment middleware who need a real live paid endpoint returning a known fixed response shape at a low cost ($0.02 USDC).

## Known failure modes

- HTTP 402 returned when no valid x402 payment header is provided — includes eip3009 extras detailing required payment
- Payment facilitated through a non-OpenX402 facilitator may be rejected
- Malformed or expired eip3009 authorization results in payment failure
- Network timeout or service unavailability returns standard HTTP 5xx error

## 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 ('deadshare'), a diagnostic note explaining this is an example paid JSON shape, the price ('$0.02'), and the title ('Dead Share'). If payment is not provided, returns HTTP 402 with eip3009 payment extras indicating what authorization is required.
