Are there any tools for checking the availability of unlimited numbers of domains?

My Godaddy account executive has an internal tool that allows him to check an unlimited number of domains to see if they are available. Whereas the public Godaddy tool limits to 500 domains.

Are there any tools, free or commercial, like this for the general public? It doesn't have to be something where the result is necessarily insant, it could give the result in batches.

Still would like to know if anyone has info on this. Again, it could be a paid tool or software.

I was just using this PHP script for a modified application. Hope it helps!

PS : There are quite a few strange characters which need to be removed to make that work.

I use the name.com bulk search, it can be slow but it doesn't have a limit
