You're not missing anything. You can run a content-owner YouTube Analytics API report and use the uploaderType
as a filter, to find stats about all the videos underneath that content owner that have a specific uploader type value. You can't request uploaderType
as a dimension in a request with a video==
or channel==
filter, though.
The matrix of supported parameters is at https://developers.google.com/youtube/analytics/v1/content_owner_reports#Reports
