## 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 is-8-8-8-8-down-check-90a5b5e9
```

Example prompt: Hey, can you check if 8.8.8.8 is actually down right now or if it's just a problem on my end — I need to know if it's a global outage?

## When to prefer this

Use this endpoint specifically when a user or agent suspects 8.8.8.8 (Google's public DNS) is unreachable and needs to distinguish between a local network issue and a global outage. It is preferable over generic ping tools because it runs from Cloudflare's global edge, provides TLS validation, and includes HTTP-layer diagnostics including redirect resolution and server headers.

## Known failure modes

- If 8.8.8.8 is genuinely unreachable, the endpoint may return a down verdict with no HTTP status or response time
- TLS check may fail if the IP serves no valid HTTPS endpoint
- Network timeouts at Cloudflare's edge could produce inconclusive results
- The endpoint itself may return an error if the monitoring infrastructure is unavailable

## How this service works

Is 8.8.8.8 down right now? Live check from Cloudflare's edge: HTTP status, response time, final URL after redirects, server header and whether the TLS certificate is valid, with an up/down verdict. Call it when a user or agent says "8.8.8.8 isn't loading" to tell a real outage from a local problem. $0.01 per check.

## Output

Returns a JSON object with the HTTP status code, response time in milliseconds, final URL after any redirects, the server response header, whether the TLS certificate is valid, and a clear up/down verdict for 8.8.8.8.
