Overview

The Halo API gives you access to official stats and metadata for Halo 5 and Halo Wars 2, including player profiles, match history, and game metadata. You need a free API key from the Halo Developer Portal to get started. It is a great choice for building stat trackers, leaderboards, or fan companion apps.
