Is there any feature or api provided by YouTube so that we can have a count of total number of likes & dislikes on any channel.
For ex: Considering the example of "TED" YouTube channel can we have details that how many likes,dislikes are there on the channel (i.e. summing all the videos likes& dislikes).
I don't think there is. On its api reference, at the time of this writing, in the channels section there is only the "viewCount", "commentCount", "subscriberCount", "hiddenSubscriberCount" and "videoCount" as statistics that can be obtained from a channel.
