Live viewer count API

You can now display concurrent viewer counts in your own UI by calling the live viewer count API. The endpoint returns the current number of viewers watching an active live stream in your workspace, so you can render audience size directly in your player UI, broadcast console, or admin dashboards.

Highlights:

• Per-stream concurrent viewer count for every active live stream in your workspace.
• Multi-tenant friendly — creator attribution is captured against playback sessions so platforms can attribute viewer counts back to the originating publisher.
• Clean responses for streams that are not currently active, instead of error responses.

Reliability fixes that landed alongside this release:

• Resolved a 500 error on the viewer count endpoint when a stream was idle.
• Removed the previous cap on viewer aggregation so large broadcasts return accurate totals.

For full request and response details, see the live viewer count API in the FastPix API reference.
