Is there a way for me to determine if a domain has been registered by the client?

I'm interested in creating a Web app that allows users to enter a domain name and then uses JavaScript to check its availability. I'm wondering if there's a method to do this without relying on my own hosting server. Is it possible to send an AJAX request directly from the user's browser to a web service that can query domain availability? If so, does anyone know of such a service?

Answer №1

One effective method is utilizing the ajaxwhois service which operates on an ajax framework. jQuery's .ajax function can be employed for this purpose.

If you wish to initiate a domain search automatically, simply access the following URLs: or

Take a look at this:

I have integrated reg-dom-libs (http://www.dkim-reputation.org/regdom-libs/) into both Javascript and Python.

Answer №3

If you're in need of a domain lookup API service, one option to consider is Dynadot's offering (check out ). While I'm not aware of any that support callbacks, I haven't delved into the documentation much either.

Based on what I can see, it seems like you'd have to initiate the request server-side (using PHP or similar) and then send the results back to the user (most likely via AJAX). It's not entirely client-side like JSONP, but should still serve its purpose effectively.
