📺 Streamer & Stream Metadata Each transcript record includes platform, title, description, author, author_id, start_time, and verified status — providing full broadcast context alongside the transcribed content.

👥 Real-Time Engagement Signals Extract follower_count, like_count, and view_count at capture time — enabling concurrent intelligence on audience reach and engagement for influencer research and live content analytics.

🔗 Recording URL Capture The record_url field delivers the video file URL when available — enabling downstream video processing, archiving, and multi-modal content analysis workflows.

📡 1,000+ Platform Support Beyond TikTok Live, YouTube Live, and Twitch — this API supports any platform exposing a public live stream URL, including news broadcasts, investor conferences, and industry event streams.
