# Room Cover

> Get the high-quality cover image (thumbnail) URL of an active live stream. Returns the same image TikTok displays on the live feed before a user taps to watch.

## `GET` `/webcast/room_cover`

Get the high-quality cover image (thumbnail) URL of an active live stream. Returns the same image TikTok displays on the live feed before a user taps to watch.

**Image quality:** Returns the highest resolution available from TikTok's CDN. Cover images are typically 720x960 or higher, served as JPEG/WebP from TikTok's image CDN.

**Use cases:** Building live stream galleries, social media embeds, notification cards with stream previews, or monitoring dashboards that show stream thumbnails alongside viewer counts.

**Note:** Cover images are set by the streamer before going live. If no custom cover is set, TikTok uses a default or auto-generated thumbnail. Returns an error if the user is not currently live.
