How this service works
Change watch for dns a via adguard: 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 DNS A record answer from AdGuard DNS, a boolean 'changed' flag indicating whether the result differs from the previous call for the same domain, a list of fields that changed with before/after values, and a timestamp of when the record was last seen. Previous results are retained for 90 days.
Example use cases
Detect unexpected IP address change
“Watch the A record for api.mycompany.com via AdGuard DNS and tell me if the IP address has changed since we last checked — show me the before and after values if it did.”
Security monitoring for domain hijacking
“Check whether the A record for mybank.com has changed since the last lookup through AdGuard — I want to know if someone may have hijacked the domain.”
Scheduled deployment verification
“After our deploy, check if the A record for app.ourproduct.io has updated to the new IP yet compared to what AdGuard returned last time, and tell me what changed.”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/watch/dns/a/via/adguard?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to detect changes in DNS A records specifically as resolved by AdGuard DNS (which applies privacy/ad-filtering), rather than a plain lookup. Prefer this over raw DNS lookup endpoints when you want change detection with historical comparison, before/after diffs, and the ability to schedule recurring monitoring. Choose over other watch endpoints when AdGuard's filtered DNS perspective is relevant (e.g. detecting if a domain is newly blocked or resolved differently by AdGuard vs other resolvers).
Side effects
- Domain not previously checked — no baseline to compare against, change flag will be false or absent
- Domain does not exist — NXDOMAIN response returned
- AdGuard DNS unreachable — upstream DNS resolver error
- Invalid domain input — malformed query parameter
- Rate limits or payment failure — $0.02 USDC per check required
