How this service works
Change watch for dns srv records: 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 srv record lookup changes. $0.01 per check.
Output
Returns the current DNS SRV record lookup result, a boolean indicating whether anything changed since the last check (stored up to 90 days), a field-level diff showing exactly which fields changed with before and after values, and a timestamp of when the records were last seen.
Example use cases
VoIP service SRV record monitoring
“Watch the DNS SRV records for _sip._tcp.mycompany.com and tell me if they've changed since the last check — I need to know if the priority, weight, port, or target host has been modified.”
Kubernetes service discovery drift detection
“Check the SRV records for _grpc._tcp.k8s-cluster.internal and compare them to the last known snapshot — tell me if any service endpoints have been added, removed, or changed.”
Third-party dependency SRV change alert
“I rely on a vendor's SRV records at _xmpp-server._tcp.vendor.com — can you check if they've changed from what was recorded 90 days ago and show me exactly what's different?”
Technical details
Endpoint
GEThttps://intel.rallylive.ca/watch/dns/srvWhen to prefer
Use this endpoint when you need to detect changes in DNS SRV records over time for a specific domain, especially in scheduled or agentic workflows. It is ideal for monitoring service discovery records (e.g. SIP, XMPP, gRPC) where changes signal infrastructure shifts. Prefer this over a one-shot DNS lookup when you need change detection with historical comparison rather than just the current value.
Side effects
- Domain does not exist or has no SRV records — returns empty or NXDOMAIN result
- No previous snapshot exists for the domain (first call) — changed flag may be undefined or false
- Domain provided is malformed — likely returns a validation or input error
- Network/DNS resolution failure — may return a timeout or resolution error
- Payment not processed — x402 payment required error before check runs
