# is-quad9-net-down

> is-quad9-net-down is a paid API for AI agents from monitor.intel.rallylive.ca, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-02).

Performs a live HTTP check from Cloudflare's edge to determine if quad9.net is currently up or down, returning status code, response time, TLS validity, and a clear verdict.

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 is-quad9-net-down-37855337
```

Example prompt: Can you check if quad9.net is actually down right now, or if it's just a problem on my end? I need to know if there's a real outage.

## When to prefer this

Use this endpoint when you need to determine from a neutral external vantage point (Cloudflare edge) whether quad9.net specifically is experiencing a real outage versus a local or ISP-level connectivity issue. Prefer this over generic uptime tools when the user explicitly references quad9.net or Quad9 DNS service.

## Known failure modes

- quad9.net is genuinely down — returns down verdict with failed HTTP status
- TLS certificate invalid or expired — flagged in response but check still completes
- Redirect loop or unexpected final URL — captured in final URL field
- Monitor service itself is unreachable — no response or timeout error
- Rate-limiting or payment failure — check not executed

## How this service works

Is quad9.net 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 "quad9.net isn't loading" to tell a real outage from a local problem. $0.01 per check.

## Output

Returns an HTTP status code, response time in milliseconds, final URL after any redirects, server header value, TLS certificate validity status, and a plain up/down verdict indicating whether quad9.net is currently accessible from Cloudflare's edge network.
