# is-ip-bt-watch

> is-ip-bt-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 2026-10-10).

Monitors whether an IP address belongs to BT (British Telecom) 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 is-ip-bt-watch-687a64a8
```

Example prompt: Keep an eye on 81.141.22.5 and let me know if its BT classification ever changes — compare each check against the last result and flag any differences with what changed and when it was last seen.

## When to prefer this

Use this endpoint when you need to continuously monitor whether a specific IP address is classified as a BT (British Telecom) IP and want to be notified only when that classification changes, rather than re-processing static results. Ideal for scheduled polling workflows where detecting change events matters more than repeated identical lookups. Prefer this over a one-shot BT IP check when change alerting and historical comparison are required.

## Known failure modes

- IP parameter missing or malformed — returns validation error
- No previous call stored for this IP (first call) — 'changed' will be undefined or false with no before/after diff
- IP is valid but BT lookup fails transiently — may return error or stale result
- Result older than 90 days purged — treated as first-time check with no history

## How this service works

Change watch for is ip bt: 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 BT classification answer (true/false), a 'changed' boolean indicating whether the result differs from the previous call, a list of fields that changed with their before and after values, and the timestamp of when the IP was last seen. Historical results are retained for 90 days.
