How this service works
Change watch for dns cname via cloudflare: 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 call (stored up to 90 days), a list of changed fields with before/after values, and a timestamp of when the record was last seen.
Example use cases
CDN migration detection
“Watch the CNAME record for mystore.com via Cloudflare and alert me if it changes — I need to know if anyone redirects it away from our CDN provider.”
Phishing or hijack alerting
“Monitor the CNAME for login.mybrand.com using Cloudflare DNS and tell me immediately if the record ever changes — that could mean someone hijacked it.”
Deployment verification polling
“Check whether the CNAME record for staging.myapp.io via Cloudflare has changed since the last time you checked, and show me the before and after values if it has.”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/watch/dns/cname/via/cloudflare?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to detect changes to DNS CNAME records specifically as resolved by Cloudflare, with built-in diff tracking across calls. Prefer it over a plain DNS CNAME lookup when you want change detection logic, before/after comparisons, and scheduling-friendly alerting without maintaining your own state.
Side effects
- Domain not found or has no CNAME record — returns empty answer with no change data
- First call for a domain — no previous result to compare against, so 'changed' may be false or undefined
- Cloudflare DoH unavailable — upstream DNS resolution failure
- Domain input missing or malformed — request error
- Previous result expired after 90-day retention window — treated as first call
