## 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 qonoro-url-health-check-9cbf0781 -d '<json body>'
```

Example prompt: Can you check if https://docs.example.com/api/reference is actually reachable right now, and tell me its HTTP status, whether it redirects anywhere, and whether the SSL certificate is valid and when it expires?

## When to prefer this

Use this endpoint when you need a quick, structured health snapshot of a single URL — including SSL status, redirect following, and response time — in one call. Prefer it over generic HTTP ping tools when you need certificate expiry details or redirect chain visibility alongside uptime status.

## Known failure modes

- URL is unreachable or DNS does not resolve — returns error indicating the host could not be contacted
- Invalid or malformed URL input — returns validation error
- Request timeout if the target server is very slow — returns timeout error
- SSL handshake failure reported as SSL invalid
- Non-HTTP/HTTPS schemes may be unsupported

## How this service works

Check URL health: HTTP status code, redirect chain, SSL certificate validity and expiry date, content type, and response time. HTTP and SSL inspection. Sub-second. x402-native.

## Output

Returns the HTTP status code, full redirect chain (if any), SSL certificate validity flag, certificate expiry date, detected content type, and response time in milliseconds for the given URL.
