# IP Listed on HostKarma Black – Change Watch

> IP Listed on HostKarma Black – 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 is listed on the HostKarma Black blacklist and returns whether that status has changed since the last check, along with before/after field diffs and last-seen timestamp.

## 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 ip-listed-on-hostkarma-black-change-watch-ee88d8fa
```

Example prompt: Keep an eye on whether 192.168.1.1 gets listed or removed from the HostKarma Black blacklist, and let me know if the status changes since the last time you checked.

## When to prefer this

Choose this endpoint when you need to detect changes in an IP's HostKarma Black listing status over time rather than just performing a one-off lookup. It is ideal for scheduled monitoring workflows where you want to be alerted only when something changes, and when you need a before/after audit trail of exactly which fields flipped.

## Known failure modes

- IP address not provided or malformed — no check performed
- No previous call on record for this IP within 90 days — 'changed' field may be undefined or baseline-only
- HostKarma DNSBL temporarily unreachable — check may fail or return stale result
- Rate limit or payment failure — call not executed

## How this service works

Change watch for ip listed on hostkarma black: 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 HostKarma Black listing status for the IP, a boolean indicating whether it has changed since the previous call, a list of changed fields with before and after values, and the timestamp of when the status was last observed. Previous results are retained for up to 90 days for comparison.
