# StackPath IP Change Watch

> StackPath IP Change 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 2026-10-13).

Monitors whether a given IP address belongs to StackPath's network, detecting and reporting changes since the last check with before/after diff and timestamp.

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 stackpath-ip-change-watch-1e75bb71
```

Example prompt: Keep an eye on whether 198.51.100.42 is a StackPath IP and let me know if its status changes — compare it against the last time you checked and show me what changed.

## When to prefer this

Use this endpoint when you need change-detection semantics — not just a one-time lookup, but a diff against a stored prior result for the same IP. Ideal for scheduled polling workflows, alerting pipelines, or any scenario where you want to know if an IP's StackPath affiliation has shifted since the last observation. If you only need the current status without change tracking, a non-watch variant would be simpler.

## Known failure modes

- Invalid or missing IP address parameter returns an error
- IP never previously checked returns no prior state (no diff available)
- Prior result older than 90 days has been purged, so comparison is unavailable
- Network or upstream DNS failure may cause the check itself to fail
- Payment failure (insufficient USDC) blocks the call

## How this service works

Change watch for is ip stackpath: 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 StackPath IP check result (true/false), a changed boolean indicating whether the result differs from the previous check (stored up to 90 days), an array of changed fields with before/after values, and a last-seen timestamp.
