Adds the following meta fields to the REST API. 
– <code>_yoast_wpseo_title</code> (Yoast) 
– <code>rank_math_title</code> (Rank Math) 
– <code>_aioseo_title</code> (All-In-One SEO)
This allows apps like https://zyppy.com to make changes to your SEO titles (once you provide an Application Password).

WordPress SEO REST API

Allows the REST API to manage meta fields from common SEO plugins

Jeff Starr

Does one thing: Completely disables the WordPress REST API for visitors who are not logged into WordPress. No configuration required.
Important: This plugin completely disables the WP REST API for visitors who are NOT logged in to WordPress. So not recommended if your site needs the WP REST API for any non-logged users.
👉 The fast, simple way to prevent abuse of your site’s REST/JSON API 
👉 Protects your site’s REST data from all non-logged users and bots 
👉 Uses only 4KB of code, so super lightweight, fast, and effective
<h3>Features</h3>
<ul>
<li>Disable REST/JSON for visitors (not logged in)</li>
<li>Disables REST header in HTTP response for all users</li>
<li>Disables REST links in HTML head for all users</li>
<li>100% plug-and-play, set-it-and-forget solution</li>
</ul>
How does it work?
This plugin completely disables the WP REST API unless the user is logged into WordPress.
<ul>
<li>For logged-in users, WP REST API works normally</li>
<li>For logged-out users, WP REST API is disabled</li>
</ul>
What happens if logged-out visitor makes a JSON/REST request? They will get only a simple message:
<pre><code>rest_login_required: REST API restricted to authenticated users.
</code></pre>
This message may customized via the filter hook, <code>disable_wp_rest_api_error</code>. Check out <a href="https://wordpress.org/support/topic/not-entirely-for-non-techies/#post-12014965" rel="ugc">this post</a> for an example of how to do it.
<h3>Privacy</h3>
This plugin does not collect or store any user data. It does not set any cookies, and it does not connect to any third-party locations. Thus, this plugin does not affect user privacy in any way. If anything it improves user privacy, as it protects potentially sensitive information from being displayed/accessed via REST API.
