Channel Data

Look up rich metadata for any YouTube channel by ID. All endpoints take a 24-char channel ID (UCxxxxxxxxxxxxxxxxxxxxxx). If you only have a @handle or URL, resolve it first via one of the search endpoints or the resolve endpoint.

GET /api/channels/:channel_id/about

Everything from a channel's About page in one call — name, description, subscriber and view counts, country, language, join date, topics, social links, trailer, banner, and more.

Path Parameters

Name	Type	Description
channel_id	string	24-char YouTube channel ID (starts with `UC`).
