How this service works
Change watch for dns cname 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 CNAME record answer, a boolean 'changed' flag indicating whether it differs from the previous check (stored up to 90 days), a list of fields that changed with their before and after values, and a timestamp of when the record was last seen.
Example use cases
Security alert on CNAME hijack
“Watch the CNAME record for mycompany.com via CleanBrowsing and alert me immediately if it changes — I'm worried about someone hijacking our DNS.”
CDN migration verification
“We just migrated our CDN and updated the CNAME for shop.example.com — can you check via CleanBrowsing whether the CNAME has changed from what it was before and show me the before and after?”
Scheduled CNAME drift monitoring
“Every hour, check if the CNAME record for api.mysite.com has changed according to CleanBrowsing and report back any differences with what fields changed and when it was last seen.”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/watch/dns/cname/via/cleanbrowsing?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need change-detection semantics on top of a raw CNAME lookup specifically answered by CleanBrowsing's security-filtered DNS resolver. It is ideal for scheduled polling workflows where you want to be alerted only when the CNAME value drifts, rather than inspecting raw records every time. Prefer it over a plain CNAME lookup endpoint when historical comparison, diff output, and a 'changed' flag are required.
Side effects
- Domain not provided or invalid — query fails with input validation error
- No previous check stored (first call) — 'changed' may be null or false with no diff available
- CleanBrowsing resolver unreachable — lookup fails or times out
- Domain has no CNAME record — returns empty record set with no diff
- Stored result expired after 90 days — baseline lost, treated as first call
