## 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-ticket-24-delta-diagnostic-endpoint-42274f4b
```

Example prompt: Run the Ticket 24 Delta x402 diagnostic to test whether my payment flow is working correctly — I want to see the paid JSON response for SKU ticket24delta via OpenX402.

## When to prefer this

Use this endpoint specifically when you need to test, debug, or validate an x402 HTTP payment protocol integration using the OpenX402 facilitator and USDC (eip3009). It is purpose-built for diagnosing x402 payment gating behavior — not for general data retrieval or production use cases. Choose this over generic HTTP testing tools when you need to verify that paid-SKU access control, 402 responses, and eip3009 payment extras are functioning correctly end-to-end.

## Known failure modes

- HTTP 402 with eip3009 extras if no valid x402 payment header is provided
- Facilitator rejection if a non-OpenX402 facilitator is used
- Malformed payment header results in 402 error
- Missing or invalid properties parameter may return error response
- Network timeout if endpoint is unavailable

## How this service works

Paid x402 diagnostics. Unpaid paid-SKU requests return HTTP 402 with eip3009 extras. Facilitator: OpenX402 only.

## Output

Returns a JSON object containing the SKU identifier ('ticket24delta'), a human-readable title ('Ticket 24 Delta'), the price ('$0.25'), and a diagnostic note. If the request is unpaid or the payment header is missing/invalid, returns HTTP 402 with eip3009 payment requirement extras specifying how to pay via USDC.
