# is-ip-att-watch

> is-ip-att-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 AT&T and alerts on changes by comparing current results with the previously stored check from up to 90 days ago.

## Facts

- Endpoint: GET https://ip.intel.rallylive.ca/watch/ip/is/att?utm_source=zero.xyz
- Price: $0.02/call
- Payment: x402

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-att-watch-f3a959e9
```

Example prompt: Keep an eye on 12.34.56.78 and let me know if its AT&T status ever changes — compare it against the last result you have on record for it.

## When to prefer this

Choose this endpoint when you need to detect changes in AT&T IP ownership over time rather than just a one-time lookup. Ideal for scheduled monitoring workflows where you want to be alerted only when something changes, reducing noise from repeated identical checks. Prefer over a simple is-ip-att lookup when historical comparison and change diffing are required.

## Known failure modes

- IP not previously checked — no prior state to compare against, changed will be false or unavailable
- Invalid or malformed IP address input — returns error
- Private/reserved IP ranges may return no meaningful result
- 90-day history window exceeded — prior state purged, no diff available
- Network timeout reaching the AT&T WHOIS/RDAP data source

## How this service works

Change watch for is ip att: 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 boolean answer for whether the IP belongs to AT&T, a 'changed' true/false flag, the specific fields that changed with before and after values, and a timestamp for when the IP was last seen. Historical state is retained for 90 days per IP.
