How this service works
Change watch for ip listed on spamhaus xbl: 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 XBL blacklist status for the IP, a boolean indicating whether the status has changed since the previous check (stored up to 90 days), a list of fields that changed with before and after values, and a timestamp of when the IP was last seen.
Example use cases
Email server IP reputation monitoring
“Watch the Spamhaus XBL status for my mail server at 203.0.113.15 and alert me if it gets listed or delisted since my last check.”
Compromised host detection alerting
“Check if 198.51.100.77 has changed its Spamhaus XBL blacklist status — I want to know immediately if it shows up as a botnet or exploit source.”
IP reputation change audit
“Has the Spamhaus XBL listing for 192.0.2.100 changed at all since the last time you looked? Show me what changed and when it was last seen.”
Technical details
Endpoint
GEThttps://ip.intel.rallylive.ca/watch/ip/blacklist/spamhaus-xbl?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to continuously monitor a specific IP address for changes in its Spamhaus XBL blacklist status, particularly in scheduled/polling workflows. Prefer this over a simple point-in-time check when you care about detecting transitions (listed → unlisted or vice versa) and want diff-style before/after output. Ideal for email deliverability monitoring, abuse detection pipelines, or alerting systems that trigger only on change events.
Side effects
- IP address not provided or malformed — query fails with validation error
- No previous check stored (first call for that IP) — 'changed' field defaults to false or undefined with no before/after values
- Spamhaus XBL DNS lookup failure — may return error or stale result
- Results older than 90 days are purged — historical comparison unavailable
- Payment not processed — endpoint returns 402 Payment Required
