Chartbeat is a real-time content analytics and audience-engagement platform built for digital publishers, media brands, and editorial teams. It measures how audiences read, watch, and engage with content the moment it is published, reporting live traffic, engaged time, loyalty, video engagement, and headline performance. Beyond its dashboards, Chartbeat exposes public HTTP APIs: a Real-Time API for live traffic and video data updated every three seconds, a Historical (Advanced Queries) API for summary traffic reporting, and Headline Testing, Conversion, and Data Lab APIs, plus JavaScript, iOS, Android, and React Native tracking SDKs for data collection. Authentication is via an account API key sent in the X-CB-AK header.
