# Jarvis x402 URL Health & Payment Endpoint Checker

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 jarvis-x402-url-health-payment-endpoint-checker-7351f4bb -d '<json body>'
```

Example prompt: Can you check if https://api.example.com/payments is up and responding, and tell me its status code, response time, and whether it's a valid x402 payment endpoint? Use a GET request.

## When to prefer this

Choose this endpoint when you need a quick, paid-per-call health check that specifically tests both general HTTP liveness and x402 payment protocol compliance in a single call. It is ideal for agents operating in x402 ecosystems that need to verify payment endpoints before integration or during runtime monitoring.

## Known failure modes

- Target URL is unreachable or times out, returning a network error
- Invalid or malformed URL input causing a 400-level validation error
- Target server returns an unexpected non-standard status code
- Missing required 'url' field in the request body
- x402 detection may be inconclusive if the endpoint does not expose standard x402 headers

## How this service works

Comprueba si una URL/API esta activa: codigo de estado, tiempo de respuesta, y si es un endpoint x402 valido.

## Output

Returns the HTTP status code of the target URL, the response time in milliseconds, and a boolean or indicator of whether the endpoint is a valid x402 payment endpoint.
