## 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-pagtotal-diagnostic-0ca893e5
```

Example prompt: Can you call the pagtotal diagnostic endpoint on OpenX402 using a GET request and show me what the paid JSON payload looks like — or show me the 402 payment challenge with EIP-3009 details if payment hasn't been attached?

## When to prefer this

Choose this endpoint when you need to test, diagnose, or demonstrate the x402 micropayment protocol flow — specifically to observe the HTTP 402 + EIP-3009 challenge structure or to confirm that a paid x402 call through the OpenX402 facilitator succeeds and returns the expected diagnostic payload.

## Known failure modes

- HTTP 402 returned when no valid x402 payment token is provided — includes EIP-3009 payment challenge details
- Requests using unsupported HTTP methods (POST, PUT, PATCH) are rejected
- Invalid or wrong facilitator_base URL may cause payment verification to fail
- Expired or already-used EIP-3009 authorization tokens rejected by the facilitator

## 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 ('pagtotal'), a human-readable title ('Pag Total'), the price ('$0.03'), and a diagnostic note. If the request lacks valid payment, returns HTTP 402 with EIP-3009 payment challenge extras specifying how to authorize USDC payment via the OpenX402 facilitator.
