That's a touchy one. Domain Name registrars are a little leery of automated tools, since such things have been unleashed on their servers with punitive effect. Plus the primary users of automated registry inquiries are domain squatters. So web services are not something I'd expect to find as much of as for other similar activities. In fact, I believe that some registrars will even throttle requests, so even if you use an app like "wget" or "whois", you may only be permitted a limited number of inquiries within a given time period.
The secret of how to be miserable is to constantly expect things are going to happen the way that they are "supposed" to happen.
You can have faith, which carries the understanding that you may be disappointed. Then there's being a willfully-blind idiot, which virtually guarantees it.
