RESTless

RESTless is a tiny WordPress plugin which disables access to the REST API (available in WordPress since version 4.4) for non-authenticated users.
This prevents usage of the REST API by the general public and limits access to those with login credentials. No REST for the wicked.

It also supports WordPress Multisite installations.
