Currently there is no featured_media image in WordPress json output with this plugin it is added to your WordPress kernel and you can also get featured_media image of each post
<h3>Arbitrary section</h3>
You may provide arbitrary sections, in the same format as the ones above. This may be of use for extremely complicated 
plugins where more information needs to be conveyed that doesn’t fit into the categories of “description” or 
“installation.” Arbitrary sections will be shown below the built-in sections outlined above.
<h3>A brief Markdown Example</h3>
Ordered list:
<ol>
<li>Some feature</li>
<li>Another feature</li>
<li>Something else about the plugin</li>
</ol>
Unordered list:
<ul>
<li>something</li>
<li>something else</li>
<li>third thing</li>
</ul>
Here’s a link to <a href="https://wordpress.org/" title="Your favorite software" rel="ugc">WordPress</a> and one to <a href="https://daringfireball.net/projects/markdown/syntax" title="Markdown is what the parser uses to process much of the readme file" rel="nofollow ugc">Markdown’s Syntax Documentation</a>. 
Titles are optional, naturally.
Markdown uses email style notation for blockquotes and I’ve been told:
<blockquote>
Asterisks for emphasis. Double it up for strong.
</blockquote>
<pre><code><?php code(); // goes in backticks ?>
</code></pre>

Allow Links from the Link Manager to be manipulated and retrieved using the REST API.
This plugin makes the following endpoints available:
<ul>
<li><code>/wp-json/wp/v2/links</code> – List details for all links, or create a new link.</li>
<li><code>/wp-json/wp/v2/links/<id></code> – List details for a particular link ID, update a link, or delete a link.</li>
</ul>
For more information about the REST API as a whole, refer to the <a href="https://wordpress.org/plugins/rest-api/" rel="ugc">REST API plugin</a>.
Note: This plugin requires the <a href="https://wordpress.org/plugins/rest-api/" rel="ugc">REST API plugin</a>.
