## 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-claimkit-paid-diagnostic-endpoint-cf3db7e0
```

Example prompt: Run a live x402 payment diagnostic against the ClaimKit endpoint — I want to see what the paid JSON payload looks like after settling 0.20 USDC through the OpenX402 facilitator.

## When to prefer this

Use this endpoint specifically when you need to test or demonstrate a live x402 micropayment flow using the OpenX402 facilitator with USDC on-chain payments. It is ideal for developers integrating the x402 payment protocol who want a real, low-cost ($0.20 USDC) paid endpoint to validate EIP-3009 authorization, HTTP 402 challenge/response behavior, and facilitator configuration — not for production data retrieval.

## Known failure modes

- HTTP 402 returned when no valid x402 payment token is provided, along with EIP-3009 payment authorization details
- Payment settled through a facilitator other than OpenX402 may be rejected
- Malformed or expired EIP-3009 authorization token causes payment verification failure
- Network timeout or server unavailability returns a 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 identifier ('claimkit'), a human-readable title ('Claim Kit'), the price ('$0.20'), and a diagnostic note. If payment has not been made, returns HTTP 402 with EIP-3009 payment challenge metadata specifying how to authorize payment via USDC.
