I'm making an online calculator, and one thing I got stuck - how to check is domain (submitted by user) available or not and show user the result without page reload. If someone know how to do it, please tell me how :)

I don't think you can get it for free. There's Whois API as an example of a for-money service. Even that one, however, doesn't have a JSONP API.

Because such services are not free, you'd generally have to provide them with some sort of API key for authentication and billing. Therefore, you certainly wouldn't want that embedded in your client-side code anyway.
