How this service works
Change watch for dns a via cleanbrowsing: runs the check, compares it with the result from your previous call for the same domain (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 DNS A record answer from CleanBrowsing, a boolean 'changed' flag, a list of fields that changed with before/after values, and a timestamp of when the record was last seen. Previous results are retained for 90 days for comparison.
Example use cases
Detect DNS hijacking on production domain
“Watch the DNS A record for mybusiness.com via CleanBrowsing and alert me if it changes — I want to know the before and after IP addresses immediately if someone redirects my domain.”
Track CDN IP rotation for a competitor
“Check if the A record for competitor.com as seen by CleanBrowsing has changed since the last time you looked, and tell me which IPs were added or removed.”
Verify DNS propagation after migration
“I just migrated api.myservice.com to a new server — has the A record via CleanBrowsing changed yet from the old IP? Show me the current answer and whether it's different from before.”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/watch/dns/a/via/cleanbrowsing?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically want to monitor DNS A record changes as seen through the CleanBrowsing resolver (which applies content filtering), rather than unfiltered resolvers like Google or Cloudflare. Ideal for scheduled polling workflows where you need change detection with historical diffing rather than just a raw lookup. Prefer over raw DNS lookup endpoints when you need before/after comparison and change alerting.
Side effects
- Domain not previously queried — no baseline to compare against (changed may default to false or null)
- CleanBrowsing resolver unavailable — DNS query fails
- Invalid or non-existent domain — empty or NXDOMAIN response
- 90-day retention window exceeded — previous result no longer available for comparison
- Payment failure — $0.02 USDC charge not processed
