In this post I'll go through the details of the SharePoint 2013 Search REST API. This new REST service is the best way to go in a variety of application scenarious. SharePoint Apps built in JavaScript is one good example. External Applications to SharePoint that require search functionality; can also leverage this service as the endpoint for communication into the Search platform.

 

The old search.asmx SOAP web service is marked as deprecated in SP2013, and the new Search REST service is the replacement.
