# is-ip-verizon-watch

> is-ip-verizon-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).

Change-watch endpoint that checks if an IP belongs to Verizon, compares the result against the previous call (retained 90 days), and returns whether the answer changed along with before/after field diffs.

## 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-verizon-watch-764f65b3
```

Example prompt: Keep an eye on 98.123.45.67 — I want to know if it stops being a Verizon IP. Run the Verizon watch check on it and tell me if the result has changed since the last time you checked.

## When to prefer this

Choose this endpoint when you need to detect changes in Verizon ISP classification for a specific IP over time, rather than just a one-shot lookup. It is ideal for scheduled polling workflows, alerting pipelines, or audit trails where knowing *when* a carrier attribution changed (and what exactly flipped) is more important than the current value alone. Prefer a non-watch sibling endpoint if you only need the current Verizon status without historical comparison.

## Known failure modes

- Missing or invalid IP address parameter — endpoint may return an error or check the wrong host
- No previous result exists yet (first call) — 'changed' will be false/null and no diff is available
- IP address is IPv6 or malformed — may not be supported by DNSBL-style lookups
- Previous result has expired (older than 90 days) — treated as a first call with no baseline
- Network timeout from edge probe — may return an error or stale result
- Payment failure (x402) — request rejected before the check is performed

## How this service works

Change watch for is ip verizon: 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-Verizon boolean result, a 'changed' true/false flag indicating whether the answer differs from the previous call for that IP, a diff object listing which fields changed with their before and after values, and a timestamp for when the IP was last seen. Previous results are retained for 90 days per IP.
