# IP Listed on NixSpam Watch

> IP Listed on NixSpam 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 an IPv4 address is listed on the NixSpam DNSBL and alerts when its blacklist status changes between checks.

## Facts

- Endpoint: GET https://ip.intel.rallylive.ca/watch/ip/blacklist/nixspam?utm_source=zero.xyz
- 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-nixspam-watch-5ac33ccd
```

Example prompt: Keep an eye on whether 203.0.113.45 gets listed or delisted on NixSpam and let me know if anything changes from the last time you checked.

## When to prefer this

Use this endpoint when you need to detect changes in NixSpam blacklist status for an IP over time, rather than just performing a one-off lookup. It is ideal for scheduled monitoring pipelines, alerting workflows, and situations where you care about transitions (listed → delisted or vice versa) rather than the raw current status alone. Prefer over a plain DNSBL check when you need change detection with before/after diffing built in.

## Known failure modes

- Invalid or non-IPv4 address format returns an error
- No previous check stored (first call has no comparison baseline, changed will be false)
- NixSpam DNSBL query timeout or DNS resolution failure
- Payment failure via x402 protocol blocks the request
- IP not found in stored history if 90-day retention window has elapsed

## How this service works

Change watch for ip listed on nixspam: 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 NixSpam listing status for the IP, a boolean indicating whether the status changed since the last call (kept for 90 days), which specific fields changed with their before and after values, and the timestamp of when the status was last seen.
