How this service works
Change watch for dns mx via google: 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 MX DNS records as answered by Google DNS, a boolean 'changed' flag comparing to the previous call for the same domain (stored up to 90 days), the specific fields that changed with before/after values, and a timestamp of when the records were last seen.
Example use cases
Email delivery outage investigation
“Has anything changed in the MX records for acmecorp.com via Google DNS recently? Show me what the records look like now and whether they differ from last time you checked.”
Domain migration verification
“We just migrated our email to a new provider — can you check if the MX records for mybusiness.com have updated yet via Google DNS, and show me what changed?”
Scheduled MX monitoring alert
“Set up a watch on the MX records for clientdomain.net via Google DNS so I get notified the moment anything changes — I need to know the before and after values right away.”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/watch/dns/mx/via/google?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to detect changes in MX records specifically as resolved by Google DNS, want a built-in diff against a historical snapshot (up to 90 days), and need a lightweight polling/scheduling approach to alert on email infrastructure changes without managing your own state.
Side effects
- Domain not found or NXDOMAIN — returns empty records with appropriate DNS response code
- No prior check stored (first call) — 'changed' may be null or false with no before values
- Google DNS resolution failure — upstream timeout or error
- Invalid or malformed domain input — bad request error
- Records unchanged — returns current data with changed: false and no diff fields
