Our SharePoint Server MVP Destin N Joy wrote this amazing post around Rest API of SharePoint as part of his contributions in Community Day 2014. Let’s read it together:

SharePoint 2013 introduces a Representational State Transfer (REST) service that is comparable to the existing SharePoint client object models. Now, developers can interact remotely with SharePoint data by using any technology that supports REST web requests. This means that developers can perform Create, Read, Update, and Delete (CRUD) operations from their apps for SharePoint, solutions, and client applications, using REST web technologies and standard Open Data Protocol (OData) syntax.

In this article we can see some example of accessing SharePoint list data using REST service

SharePoint 2013 adds the ability for you to remotely interact with SharePoint sites by using REST. Now, you can interact directly with SharePoint objects by using any technology that supports standard REST capabilities.

To access SharePoint resources using REST, construct a RESTful HTTP request, using the Open Data Protocol (OData) standard, which corresponds to the desired client object model API. For example:

Client object model method:

List.GetByTitle(listname)

REST endpoint:

http://server/site/_api/lists/getbytitle('listname')

The client.svc web service in SharePoint handles the HTTP request, and serves the appropriate response in either Atom or JSON (JavaScript Object Notation) format. Your client application must then parse that response. The figure below shows a high-level view of the SharePoint REST architecture.
