## 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-pay-to-health-diagnostic-02444db5
```

Example prompt: Run the x402 pay-to-health diagnostic against my settlement address 0xAbC1234567890abcdef1234567890abcdef123456 and tell me if the OpenX402 facilitator is responding correctly.

## When to prefer this

Choose this endpoint when you specifically need to test or diagnose the x402 payment protocol flow using the OpenX402 facilitator, particularly when validating EIP-3009 authorization, confirming a settlement address is correctly configured, or debugging why micropayments are being rejected. Not suitable for general health checks unrelated to x402 payment mechanics.

## Known failure modes

- HTTP 402 returned when payment header is missing or invalid — expected behavior for unpaid requests, includes EIP-3009 challenge extras
- Invalid or malformed payTo address causes a 400 bad request error
- OpenX402 facilitator unavailable returns a 5xx error
- Network timeout if the facilitator is temporarily unreachable
- Payment amount mismatch (not exactly $0.03 USDC) causes payment rejection

## How this service works

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

## Output

A JSON response containing x402 diagnostic health data including facilitator status, EIP-3009 payment extras, and confirmation that the payment flow completed. If payment was not provided, returns HTTP 402 with a structured payment challenge including the required USDC amount and EIP-3009 authorization parameters.
