How this service works
Change watch for ip listed on uceprotect 3: 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 UCEProtect-3 blacklist status for the IP (listed true/false), a boolean indicating whether the result has changed since the previous call, a diff of which fields changed with before and after values, and the timestamp of when the status was last observed. Previous results are retained for 90 days for comparison.
Example use cases
Mail server IP blacklist alerting
“Check if 198.51.100.10 has changed its UCEProtect-3 listing status since the last time you checked — I want to know the moment it gets listed or delisted so I can act fast.”
Post-remediation delisting verification
“We just cleaned up the spam issue on our mail server at 203.0.113.55 — has its UCEProtect Level 3 status changed compared to before? I need to confirm it's been removed from the blacklist.”
Hosting provider IP reputation monitoring
“I manage a block of IPs for my hosting clients — can you watch 192.0.2.78 on UCEProtect-3 and tell me if its blacklist status has changed, including what exactly changed and when it was last seen?”
Technical details
Endpoint
GEThttps://ip.intel.rallylive.ca/watch/ip/blacklist/uceprotect-3?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need change detection rather than just a one-time status check — it is specifically designed for scheduled polling workflows where you want to be alerted only when the UCEProtect Level 3 listing status of an IP changes, avoiding noise from repeated identical results. Prefer this over the plain ip-listed-on-uceprotect-3 endpoint when building monitoring pipelines or automations that fire conditionally on state transitions.
Side effects
- IP address not supplied or malformed — query fails with validation error
- No previous record found for IP (first call) — changed field may be null or false by default
- DNSBL query timeout or DNS resolution failure — may return error or stale result
- IP address is IPv6 — endpoint appears to support IPv4 only
- Stored result older than 90 days purged — comparison unavailable, treated as first call
