Entity Query API fills the gap between Drupal 8's built-in RESTful Services and Views with an easy to use, out-of-the-box means for loading, filtering and paging entities in a RESTful style. Essentially, this module provides an API to the Entity QueryInterface.

Any enabled entity gets an endpoint at /entity/{entity_type} which responds to GET requests.

You can apply conditions, sorts, and ranges to your query for the given entity type.
