This plugin enables you to have a Domains Names Checker on your blog using a single shortcode. The plugin can run in 2 different search modes (AJAX search and an Instant search). Check out the Instant Search demo here
This search is a regular search, where the user needs to hit the submit button to do the search.
With this type of search the user doesn’t need to hit any submit button (that doesn’t exist anyways). A search is done as the user is typing in the domain name.
This plugin is based on 2 different API (domai.nr and Dreamhost) and you can decide to use the service you wish (defined from the plugin settings page). You can also enable the caching of the domains availability search results, and even define the caching expiration for how long you want to wait before the results are refreched.
You can also define your own registrars lists (in an HTML format) with your own affiliate links to register a new domain, that way you can make money each time a user registers a domain through your website !
This Domains Name Checker is also available as a Standalone version
