I want to fetch public youtube analytics data for any channel like Social Blade https://socialblade.com/youtube/user/tseries.
The only API I could find is the reports API providing similar data https://developers.google.com/youtube/reporting/v1/reportsbut the API uses OAuth 2.0 and does not work with the API key.
Is there any other youtube API I can use to get time-series subscriber count and video view count for any channel on youtube?
