How this service works
Change watch for ip listed on backscatterer: 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 Backscatterer listing status for the IP, a boolean indicating whether the result changed since the last call, a list of changed fields with before and after values, and the timestamp of when the IP was last seen. Previous check results are retained for 90 days.
Example use cases
Mail server IP reputation monitoring
“Check if 203.0.113.15 has changed its Backscatterer listing status since the last time you looked, and tell me what fields changed and when it was last seen.”
Newly provisioned server clearance check
“I just set up a new mail server at 192.0.2.88 — has it shown up on Backscatterer yet, and has anything changed from the previous check?”
Automated deliverability alert workflow
“Poll Backscatterer for 198.51.100.77 right now and tell me if the blacklist status changed compared to last time — I want to trigger an alert if it did.”
Technical details
Endpoint
GEThttps://ip.intel.rallylive.ca/watch/ip/blacklist/backscatterer?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to detect changes in Backscatterer DNSBL listing status over time, not just the current status. It is ideal for scheduled monitoring workflows where you want to be alerted only when something changes, rather than polling a simple check endpoint and doing your own diffing. Prefer this over a plain lookup when you need the before/after diff and change tracking built in.
Side effects
- Invalid or malformed IP address returns an error
- IP not previously checked has no prior state to compare against (first call will establish baseline)
- Results older than 90 days are expired and treated as no prior state
- Payment failure (x402) prevents the check from running
- Backscatterer DNS lookup timeout may cause transient failures
