Disable Permanently REST API

The most simple plugin to disable permanently REST API on WordPress 4.7+

RESTful Syndication allows you to automatically ingest content from other WordPress sites, using the WordPress REST API.
This can allow you to run a network of sites, which all receive the same post content.
There is a small selection of options, allowing you select the author, default post status, automatically create the appropriate terms, and set the Yoast No-Index status.
