# IP Blocklist.de Change Watch

> IP Blocklist.de 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).

Monitors whether a given IP address is listed on Blocklist.de, returning the current status, whether it changed since the last check, and which fields changed with before/after values.

## 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-blocklist-de-change-watch-07c9014b
```

Example prompt: Keep an eye on whether the IP 185.220.101.5 is listed on Blocklist.de and let me know if its status has changed since the last time you checked.

## When to prefer this

Choose this endpoint when you need to detect changes in an IP's Blocklist.de reputation over time rather than just a one-time snapshot. It is especially useful for automated alerting pipelines, scheduled monitoring jobs, or threat-response workflows where you need to know if and exactly how a blacklist listing changed since the last check.

## Known failure modes

- IP not provided or malformed — request fails with input validation error
- No previous check on record for the IP within 90 days — 'changed' may be null or treated as first-time check
- Blocklist.de upstream unavailable — may return stale or error response
- Payment not fulfilled via x402 protocol — request rejected before check runs
- Rate limiting or quota exceeded — check not performed

## How this service works

Change watch for ip listed on blocklist de: 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 Blocklist.de listing status for the IP, a boolean 'changed' flag indicating whether it differs from the previous check (stored up to 90 days), a list of fields that changed with before and after values, and a timestamp of when it was last seen.
