<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.

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.

Disable WP REST API

while the plugin si deadsimple and very low resource impact, keep in mind that there are plugins that need the rest to work with no auth (ex. contact form 7).

dead simple and efficient, but be aware

Disables the WP REST API for visitors not logged into WordPress.

Samuel Aguilera

The WordPress REST API is a great resource, but if you don’t want to use it probably you will want to close this door to your WordPress.
Unlike other popular plugins that aims to disable the REST API but only return an error, processed by the REST API, when a request is received, by default, this plugin removes all filters and actions related to WordPress REST API, and returns a 404 error for requests sent to the REST API URL endpoints, effectively blocking any use of the REST API.
Optionally you can set the REST API setting in Settings -> General page to “Logged In Only” for a less drastical action, to keep REST API access enabled but require the user to be logged in to accept the requests.
If you’re happy with the plugin <a href="https://wordpress.org/plugins/sar-disable-rest-api/reviews/?filter=5" rel="ugc">please don’t forget to give it a good rating</a>, it will motivate me to keep sharing and improving this plugin (and others).
SUPPORT: If you have any support question, please <a href="https://github.com/samuelaguilera/sar-disable-rest-api/issues" rel="nofollow ugc">create an issue at the Github repository</a>.
<h4>Requirements</h4>
<ul>
<li>WordPress 4.7 or higher.</li>
</ul>
<h4>Features</h4>
<ul>
<li>Disable WordPress core REST API for real by removing all filters and actions related to it and returning a 404 error for requests sent to REST API URL endpoints (e.g. https://example.com/wp-json/whatever ).</li>
<li>Option to require user to be logged in to use the REST API instead of completely disable it.</li>
</ul>
<h4>Usage</h4>
To disable the REST API completely simply install the plugin from the Plugins page and enable it.
If you don’t want to disable the REST API but require user to be logged in instead, go to Settings -> General page and set the REST API to option to “Logged In Only”, and click Save Changes.
You can change the option back to “Off” if you want to disable the REST API again.
To return to WordPress default, simply deactivate the plugin.
