I would like to create a simple module for my website that prints keywords and tells the user if the keyword is available to register as domain. Is there any domain name registrar who gives any kind of api to do this? I would like to show something like this:
Keyword | .com domain | .net domain
Website | not available | available - register at XX for $0.99! (<- affiliate link)
 @Anthony Hatzopoulos, @Anagio - I wasn't specific because I don't really care about the form. It can be some kind of widget that just has to be implemented or a raw api that returns data that must be processed before showing it to the user. Raw API without any interface would be the best since you can modify and control outputted data. I do realise however that if there would be any api available people would use it not to generate income for domain registrar, but to use it as free "whois" api operator. I assume that if there exists a domain registrar with such a feature - than it's propably coded in JS to secure the data.
