## 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-webhook-pass-diagnostic-d28afef4
```

Example prompt: Run the webhookpass diagnostic on the x402-tools endpoint — I want to confirm my EIP-3009 payment header is working and see the paid JSON response for the $0.18 USDC SKU.

## When to prefer this

Use this endpoint when you need a real, live x402-gated API call to test or demonstrate EIP-3009 micropayment authorization, validate your x402 client implementation, or confirm OpenX402 facilitator connectivity — specifically for the webhookpass SKU at $0.18 USDC. Prefer it over mock or sandbox endpoints when you need an actual on-chain payment settlement test.

## Known failure modes

- HTTP 402 returned if no valid x402 payment header is included — response includes EIP-3009 challenge extras
- Payment rejected if facilitator is not OpenX402
- Malformed EIP-3009 authorization results in payment failure and 402 response
- Invalid or missing 'properties' parameter may yield unexpected behavior
- Network timeout or server unavailability returns standard HTTP error codes

## 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 ('webhookpass'), a human-readable title ('Webhook Pass'), the price ('$0.18'), and a diagnostic note confirming the paid payload shape. Unpaid requests return HTTP 402 with EIP-3009 payment challenge extras instead.
