# is-ip-proofpoint-watch

> is-ip-proofpoint-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 an IP address belongs to Proofpoint's infrastructure, returning the current result, whether it changed since last check, and what fields changed with before/after values.

## Facts

- Endpoint: GET https://ip.intel.rallylive.ca/watch/ip/is/proofpoint?utm_source=zero.xyz
- Price: $0.02/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-13

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-proofpoint-watch-c9015c05
```

Example prompt: Keep an eye on 198.2.185.100 and let me know if its Proofpoint classification changes — I want to know if it was Proofpoint before and isn't anymore, or vice versa.

## When to prefer this

Use this endpoint when you need to track changes in Proofpoint IP classification over time and be alerted when status flips, rather than just doing a one-time lookup. It is ideal for scheduled monitoring workflows where you want to detect when an IP joins or leaves Proofpoint's infrastructure. Prefer the non-watch variant if you only need the current classification without change detection.

## Known failure modes

- IP not previously checked — no baseline for comparison, 'changed' will be null or false with only the current result
- Invalid or malformed IP address — likely returns an error or empty result
- Network timeout reaching the check infrastructure — call may fail or return stale data
- Previous result older than 90 days — baseline expired, comparison treated as first-time check

## How this service works

Change watch for is ip proofpoint: 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 is a Proofpoint IP, a 'changed' true/false flag indicating whether the result differs from the previous call for that IP, a list of fields that changed with their before and after values, and a timestamp of when it was last seen. Results from previous calls are retained for 90 days for comparison.
