How this service works
Change watch for dns txt 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 TXT records for the domain as answered by Google DNS, a boolean 'changed' flag, a list of fields that changed with before and after values, and a timestamp of when the current state was last seen. The previous result is retained for up to 90 days for comparison.
Example use cases
SPF Record Tampering Alert
“Keep an eye on the TXT records for mycompany.com using Google DNS — alert me if the SPF record changes at all, and show me what it was before versus what it is now.”
Domain Ownership Verification Monitoring
“Check whether the domain verification TXT record on startup.io has changed since last time — I need to know if a third-party service token got rotated or removed.”
DKIM Key Rotation Detection
“Watch the TXT records for newsletter.acme.com via Google DNS and tell me the moment the DKIM key changes, including what the old and new values are.”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/watch/dns/txt/via/google?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to detect changes in DNS TXT records specifically as seen by Google's public resolver (8.8.8.8), which is widely trusted and globally distributed. Prefer this over Mullvad or AliDNS watch variants when you want results from a resolver your audience or services are likely to use. Ideal for scheduled polling workflows where you want diff-based change alerts rather than raw record lookups.
Side effects
- Domain not found or NXDOMAIN — returns empty records with no change data
- No previous result stored (first call) — returns current answer but changed=false or null with no before values
- Google DNS resolution failure or timeout — may return an error or empty response
- Domain input missing or malformed — request fails with validation error
- 90-day history expired — comparison baseline lost, treated as first call
