YouTube channel email

Reveal the protected public business email from a YouTube channel's about panel using a managed signed-in browser.

POST /v1/youtube/channel/email

Authentication

Requires a managed youtube.com login on kernel. Browsable automatically uses a saved login when one is available.

If your team does not already have a usable login, the API returns 428 Authentication required with a hosted_url. Open that URL, finish sign-in, then retry the same request.

Request Parameters

Name	In	Type	Required	Description
captcha_timeout_ms	body	number	No	Milliseconds to wait for YouTube's captcha and email reveal flow (0-300000). Defaults to 180000.
channel_id	body	string	No	YouTube channel ID (for example UCX6OQ3DkcsbYNE6H8uQQuVA).
channel_url	body	string	No	YouTube channel URL or tab URL. Handles like https://www.youtube.com/@MrBeast and channel IDs are normalized to the requested tab.
