I have a list of domain names. I can get this list in multiple formats, such as XML, HTML, CSV etc.
I want to be able to use client-side code to check if the domain names in the list have expired.
Does anyone have any suggestion how that could be done? I have seen various links to the WhoISXML API in other stackoverflow questions, but i require the service to be free.
Any ideas if this is even doable?
