# ip-listed-on-spamhaus-zen-watch

> ip-listed-on-spamhaus-zen-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 is listed on Spamhaus ZEN DNSBL and alerts when the listing status changes compared to the previous check.

## Facts

- Price: $0.02/call
- Payment: x402

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 ip-listed-on-spamhaus-zen-watch-44687604
```

Example prompt: Keep an eye on whether 203.0.113.45 gets listed or removed from Spamhaus ZEN and tell me as soon as the status changes from what it was last time.

## When to prefer this

Use this endpoint when you need to detect changes in an IP's Spamhaus ZEN blacklist status over time, rather than just querying the current status once. Ideal for scheduled monitoring, alerting pipelines, and automation workflows where you only need to act when something changes. Prefer the non-watch variant if you only need a single one-off check without change tracking.

## Known failure modes

- IP address not provided or malformed — returns error
- No previous check exists for this IP (first call returns current status with changed=false or null)
- DNS resolution failure for the DNSBL query — may return an error or unavailable status
- Spamhaus ZEN service temporarily unreachable — returns error
- Payment not processed — request rejected with 402

## How this service works

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