WP Ajax Query allows you to query your WordPress database using the same query paramaters you would use for WP_Query, and return a JSON respresentation of the query results. This allows developers to easily interface with WordPress without having to relearn a new API.
<h3>How It Works</h3>
The Ajax Query interface would be available at http://example.com/wp-admin/admin-ajax.php?action=query
A sample jQuery request would be like: 
 $.get(ajaxurl, { action: ‘query’ }, function () { }, ‘json’);
Querying for a post: 
 $.get(ajaxurl, { action: ‘query’, p: 1 }, function () { }, ‘json’);
JSON results: 
 { 
 “id”: 1, 
 “type”: ‘post’, 
 “title”: “Hello World”, 
 “permalink”: “http:\/\/example.com\/?p=1” 
 }
Query a category: 
 $.get(ajaxurl, { action: ‘query’, cat: 1 }, function () { }, ‘json’);
JSON results: 
 { 
 “id”: 1 
 “type”: “category”, 
 “permalink”: “http:\/\/example.com\/?cat=1”, 
 “terms”: [], 
 “posts”: [] 
 }
<pre><code>terms and `posts` represents an array of either terms that are sub categories of the category, or posts belonging to the category.<h3>Why I Created It</h3>
</code></pre>
Needed a common way to query the database for posts and taxonomies across multiple plugins, and didn’t find a suitable replacement.
