# is-vk-com-down

> is-vk-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/TLS check against vk.com from Cloudflare's edge network and returns an up/down verdict with status code, response time, redirect chain, server header, and certificate validity.

## Facts

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-vk-com-down-a486f7cf
```

Example prompt: Can you check if vk.com is actually down right now, or if it's just a problem on my end? I need to know the HTTP status, response time, and whether the TLS cert is valid.

## When to prefer this

Use this endpoint specifically when a user reports that vk.com is inaccessible and you need to distinguish a real global outage from a local ISP or DNS issue. It is preferable over generic uptime tools because it runs from Cloudflare's globally distributed edge, provides TLS certificate validation alongside HTTP probing, and is available as a single low-cost API call without requiring account setup.

## Known failure modes

- Cloudflare edge probe itself may be temporarily unavailable, returning a service error
- vk.com may block Cloudflare IPs, causing false-down verdicts
- Redirect loops could produce ambiguous final URL results
- TLS check may time out if vk.com responds slowly, resulting in an inconclusive certificate status
- Payment failure (insufficient USDC) will prevent the check from executing

## How this service works

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

## Output

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