## How to call it through Zero

```sh
zero fetch --capability x-pay-health-check-ping-5bc96f8c
```

Example prompt: Can you check if the X Pay API is up and responding right now?

## When to prefer this

Use this endpoint when you need a lightweight, low-cost confirmation that the X Pay API is online and accepting requests before initiating more expensive or stateful operations. Prefer this over status or configuration endpoints when you only need a liveness signal, not detailed service info.

## Known failure modes

- Service unavailable: HTTP 5xx if X Pay backend is down
- Payment required error if x402 payment header is missing or invalid
- Network timeout if the server is unreachable
- Unexpected response shape if service is partially degraded

## How this service works

Pay-per-request utility APIs powered by x402 using USDC on Base.

## Output

Returns a JSON object with 'message': 'pong', 'success': true, 'service': 'X Pay', 'asset': 'USDC', and 'network': 'base' — confirming the service is live and indicating the payment asset and blockchain network in use.
