Hey there, how do you monitor the domain information update? Manually check or another way? Here is a tool for you. You will get email notifications when the WHOIS items and DNS records change.
It's a beta feature. Let me know if you have any advices.
I had been working on a domain tool with similar features. I put it on the back burner for my other project log.fm. Good luck with yours. Domain monitoring is super competitive!
