The REST API Console is an interactive way to explore the WordPress REST API through your normal WordPress admin. Great for learning about the API, tinkering with data on your site, or finding out what your site is exposing. (Also pairs well with a fruity red.)
You’ll need to have the WordPress REST API plugin (v2 or later) installed to use this. You can only access your local site through this plugin.
