I've tried it with the C# wrapper library, so using plain old methods and C# objects rather than touching the JSON directly. It's not too bad, but not free as far as I'm aware and the result snippets they give you are quite limited in length. Also I found it a little tricky to get good results on some queries when I tried it out.
