We'll create fresh WordPress site with Ajax Load More: REST API installed. You have 20 minutes to test the plugin after that site we'll be deleted.
The REST API extension will enable compatibility between Ajax Load More and the WP REST API plugin.
Easily access your website data (as JSON) through an HTTP REST API and display the results using the beauty of infinite scrolling with Ajax Load More.

The REST API add-on works by routing the standard Ajax Load More admin-ajax.php requests through to API endpoints for data retrieval. The data is returned as JSON, then parsed and displayed using Underscore.js styled templates on the front-end of your website.
Using a simple GET request, a JavaScript Repeater Template and a custom endpoint (/wp-json/ajaxloadmore/posts) developed specifically for Ajax Load More, users are able to access website data and infinite scroll the results using the WP REST API.
