# IP Listed on LashBack Blacklist – Change Watch

> IP Listed on LashBack Blacklist – 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 2026-10-12).

Checks if an IP is listed on the LashBack DNSBL, compares the result to the previous check (stored 90 days), and returns whether the status changed, which fields changed, and when it was last seen.

## 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-lashback-blacklist-change-watch-d3438c43
```

Example prompt: Keep an eye on whether 203.0.113.45 is listed on the LashBack blacklist and let me know if its status changes compared to the last time you checked.

## When to prefer this

Use this endpoint when you need to detect changes in an IP's LashBack blacklist status over time, rather than just a one-off lookup. It is ideal for scheduled monitoring workflows where you want to be alerted only when the listing status actually changes, avoiding noise from repeated identical results. Prefer this over a plain blacklist check when you need before/after diff data and last-seen timestamps.

## Known failure modes

- No previous check stored — first call returns no change data, only the current status
- IP address parameter not supplied or malformed — likely returns an error
- LashBack DNSBL lookup timeout or failure — may return an error or stale result
- 90-day history window expired — treated as a fresh first check with no prior comparison

## How this service works

Change watch for ip listed on lashback: 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 LashBack blacklist listing status for the IP, a boolean indicating whether the status changed since the previous call, a list of fields that changed with before/after values, and a timestamp for when the IP was last seen. Previous results are retained for 90 days for comparison.
