## 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-deny-age-195-diagnostic-endpoint-53fdacf4
```

Example prompt: Run the x402 diagnostic for the 'denyage195' SKU and show me what the paid JSON response looks like — I want to verify the payment-gated flow is working with OpenX402 as the facilitator.

## When to prefer this

Choose this endpoint when you need to test, diagnose, or demonstrate the x402 HTTP payment-gating protocol in practice, specifically with the OpenX402 facilitator and EIP-3009 payment authorization. It is best suited for developers integrating x402 into their own APIs who want a live reference implementation, or for verifying that their micropayment infrastructure works end-to-end with a $0.02 USDC USDC-denominated paid call.

## Known failure modes

- HTTP 402 returned when no valid x402 payment header is provided — includes EIP-3009 extras for payment resolution
- Invalid or expired EIP-3009 authorization results in payment rejection
- Non-OpenX402 facilitators are rejected — only OpenX402 is supported
- Malformed properties parameter may result in an error response
- Network timeout if the endpoint is temporarily unavailable

## 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 ('denyage195'), a diagnostic note clarifying this is an example paid response shape, the price ('$0.02'), and the title ('Deny Age 195'). If the request is unpaid, the endpoint returns HTTP 402 with EIP-3009 payment extras indicating the required payment.
