How this service works
Change watch for dns cname record: runs the check and compares it with the result from your previous call for the same domain (kept 90 days), returning the current answer, changed true/false, exactly which fields changed with before/after values, and when it was last seen. Call it on a schedule to be told when dns cname record lookup for a hostname changes. $0.01 per check.
Output
Returns the current CNAME record answer for the hostname, a boolean 'changed' flag indicating whether it differs from the previous check (stored up to 90 days), an itemized diff of exactly which fields changed with before and after values, and a timestamp of when the record was last seen.
Example use cases
CDN migration detection for SaaS platform
“I need to know the moment the CNAME record for cdn.myapp.io changes — run a check now and tell me if it's different from the last time you looked, with the exact before and after values.”
Security watch for brand domain hijacking
“Watch the CNAME record for secure.mybrand.com and alert me if anything has changed since the previous check — I'm worried about DNS hijacking so show me exactly which fields changed.”
Vendor handoff verification during DNS cutover
“Check whether the CNAME record for api.partner-site.com has flipped to the new target yet — compare it to the last recorded result and tell me if changed is true or false.”
Technical details
Endpoint
GEThttps://intel.rallylive.ca/watch/dns/cnameWhen to prefer
Choose this endpoint when you need change-detection semantics for a DNS CNAME record rather than just a raw lookup — it maintains a 90-day history of prior results and returns structured field-level diffs, making it ideal for scheduled monitoring workflows where you need to know exactly what changed and when, without building your own diffing logic.
Side effects
- Hostname does not exist — DNS NXDOMAIN or resolution failure returned
- No previous result stored (first call for this hostname) — changed flag may be false or undefined
- Hostname parameter missing or malformed — validation error returned
- DNS lookup timeout or upstream resolver error — transient failure
- Previous result expired (older than 90 days) — baseline lost, treated as new record
