REST API Explorer

This plugin provides an easy way to explore the currently registered REST API routes and endpoints along with parameter information for each endpoint. The plugin adds a Tools > REST API Explorer menu item which provides an interactive API exploration interface, listing REST endpoints from WordPress core as well as endpoints registered by plugins. You can provide values for endpoint parameters (where applicable) and run the endpoints in your browser.

This plugin can be installed under Plugins > Add New Plugin, either by searching for the plugin title or by downloading the plugin zip file and uploading it via the Upload Plugin feature.
