This plugin extends the <a href="https://wordpress.org/plugins/json-rest-api/" rel="ugc">WordPress JSON REST API</a> with new routes for WordPress registered menus
The new routes available will be:
<ul>
<li><code>/menus</code> list of every registered menu.</li>
<li><code>/menus/<id></code> data for a specific menu.</li>
<li><code>/menu-locations</code> list of all registered theme locations.</li>
<li><code>/menu-locations/<location></code> data for menu in specified menu in theme location.</li>
</ul>
Currently, the <code>menu-locations/<location></code> route for individual menus will return a tree with full menu hierarchy, with correct menu item order and listing children for each menu item. The <code>menus/<id></code> route will output menu details and a flat array of menu items. Item order or if each item has a parent will be indicated in each item attributes, but this route won’t output items as a tree.
You can alter the data arrangement of each individual menu items and children using the filter hook <code>json_menus_format_menu_item</code>.
An important note on WP API V2:
In V1 the routes are located by default at <code>wp-json/menus/</code> etc.
In V2 the routes by default are at <code>wp-json/wp-api-menus/v2/</code> (e.g. <code>wp-json/wp-api-menus/v2/menus/</code>, etc.) since V2 encourages prefixing and version namespacing.

This plugin adds “routes” or “endpoints” to WP REST API that allows for retrieval of 
menu data as JSON.
Updated port of “WP-REST-API V2 Menus” by Claudio La Barbera (http://www.claudiolabarbera.com)
Usage
Get all registered menus:
<pre><code>GET /wp-menus/v1/menus
https://yourwpsite.com/wp-json/wp-menus/v1/menus
</code></pre>
Get menu data as JSON from menu slug:
<pre><code>GET /wp-menus/v1/menus/{slug}
https://yourwpsite.com/wp-json/wp-menus/v1/menus/{slug}
</code></pre>
Gets the contents of a registered menu by its “slug”.
When assigning a menu a location in /wp-admin/nav-menus.php?action=locations 
the slug is the name of the menu in lowercase and without any spaces like a post slug.
If your menu name is Main Menu: 
https://yourwpsite.com/wp-json/menus/v1/wp-menus/main-menu
