Google Poly API Announced, Poly Toolkit SDK for Unreal Released
Poly Toolkit for Unreal Engine allows apps to interact directly with Poly to search, download and import objects dynamically across desktop, mobile, virtual reality and augmented reality platforms such as ARCore.

Google is supporting the launch with an example project in Unreal Engine as well as a dev site containing sample code showing how to use the API on Android and iOS, including ARCore and ARKit samples, and also a sample on how to use the API from web apps.
