# CDN IP Check Change Watch

> CDN IP Check Change Watch is a paid API for AI agents from intel.rallylive.ca, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-14).

Monitors whether an IP address belongs to a CDN or reverse proxy and alerts when that classification changes between calls.

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 cdn-ip-check-change-watch-83e15a4a
```

Example prompt: Check whether 104.21.45.67 is behind a CDN or reverse proxy right now, and tell me if anything changed since the last time you checked — which provider it is, and exactly what fields are different.

## When to prefer this

Choose this endpoint when you need to detect changes in CDN or reverse proxy status for an IP over time, rather than just a one-off check. It is ideal for scheduled polling workflows where you want to be alerted only when something changes, with exact field-level diff data. Prefer this over a single CDN check when building monitoring pipelines, security alerting systems, or infrastructure tracking dashboards.

## Known failure modes

- Invalid or malformed IP address returns an error
- IP not previously checked returns no change data for first call
- Results older than 90 days are purged, treated as first call
- Service unavailability returns HTTP error codes
- Private or reserved IP ranges may not be classified

## How this service works

Change watch for cdn ip check: runs the check and compares it with the result from your previous call for the same ip (kept 90 days), returning the current answer, changed true/false, exactly which fields changed with before/after values, and when it was last seen. Call it on a schedule to be told when is this ip a cdn or reverse proxy? detects cloudflare, akamai, fastly, cloudfront, imperva/incapsula, sucuri, stackpath, changes. $0.01 per check.

## Output

Returns the current CDN/reverse proxy classification for the IP, a boolean 'changed' flag indicating whether the result differs from the previous call, a list of exactly which fields changed with before and after values, and a timestamp of when the IP was last seen. Previous results are retained for 90 days.
