# is-ip-vercel-watch

> is-ip-vercel-watch is a paid API for AI agents from ip.intel.rallylive.ca, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-12).

Monitors whether an IP address belongs to Vercel's infrastructure and alerts you when that status changes between checks.

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-ip-vercel-watch-3167ac10
```

Example prompt: Watch the IP 76.76.21.21 and let me know if its Vercel classification ever changes — I want to know the before and after values and when it last changed.

## When to prefer this

Choose this endpoint when you need to detect changes in Vercel IP classification over time rather than just a one-shot lookup. It is ideal for scheduled monitoring workflows where you want to be alerted the moment an IP moves onto or off of Vercel's infrastructure. Prefer it over a plain is-ip-vercel check when diffing matters — you get the before/after values and a changed flag automatically without managing state yourself.

## Known failure modes

- Invalid or malformed IP address returns an error
- IP not previously checked results in no comparison data (first-run, no diff available)
- Previous result older than 90 days has been purged, so no historical comparison is possible
- Network connectivity issues may prevent the underlying Vercel IP range lookup
- Payment failure (x402) results in 402 response and no check performed

## How this service works

Change watch for is ip vercel: runs the check, compares it with the result from your previous call for the same ip (kept 90 days) and returns the current answer, changed true/false, the fields that changed with before/after values, and when it was last seen. Schedule it to be alerted when this changes. $0.02 per check.

## Output

Returns the current is-Vercel boolean result for the IP, a changed true/false flag comparing against the previous check (stored up to 90 days), the specific fields that changed with their before and after values, and the timestamp of when the IP status was last observed.
