# is-firefox-com-down

> is-firefox-com-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 firefox.com is currently up or down, returning HTTP status, response time, final URL, server header, and TLS certificate validity.

## 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-firefox-com-down-6bdbba69
```

Example prompt: Firefox.com isn't loading for me right now — can you do a live check from outside my network to see if it's actually down for everyone or just me?

## When to prefer this

Use this endpoint when a user reports that firefox.com is not loading and you need to distinguish a real global outage from a local connectivity or DNS problem. It is preferable to generic ping tools because it checks HTTP status, TLS validity, redirect chains, and server headers from Cloudflare's globally distributed edge, giving an objective external view rather than a local one.

## Known failure modes

- firefox.com itself is down, returning a 'down' verdict with associated error details
- DNS resolution failure for firefox.com at the edge
- TLS handshake failure resulting in invalid certificate flag
- Redirect loop causing failure to resolve final URL
- Timeout if firefox.com is extremely slow to respond
- Edge probe error if Cloudflare infrastructure has issues

## How this service works

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

## Output

Returns an up/down verdict for firefox.com along with the HTTP status code, response time in milliseconds, the final URL after any redirects, the server header value, and whether the TLS certificate is currently valid — all measured from Cloudflare's edge network.
