I have read all the Youtube api doc but I haven't find this answer. Is there an API to know the date and time of next premiere video of a selected channel?
One more time YouTube APIs doesn't provide a basic feature.
I recommend you to try my open-source YouTube operational API. Indeed by fetching https://yt.lemnoslife.com/channels?part=upcomingEvents&id=CHANNEL_ID you will retrieve all upcoming events of the given YouTube channel. Especially may interest you about the upcoming event:
item["videoId"] (example: yVVQai84NrI)item["upcomingEventData"]["startTime"] (example: 1717106417)item["title"]["simpleText"] (example: Another "Premiere" video)item["thumbnail"]["thumbnails"] (example: url, width, height)Channels to test:
UCv_LqFI-0vMVYgNR3TeB3zQ (should at least return BvVOl19eo1o)UCv_LqFI-0vMVYgNR3TeB3zQ (should at least return 1PpAgFFP9K4)
