Are there limits for retrieving text from Youtube? Can I get content of comments?

Question

I am student and I am building Project that can retrieve textual features from YouTube videos using YouTube API.

Are there limits to search for videos and retrieve its information per day?

Can I retrieve all comments of each video or just its number?

I will be grateful for your help.

Answer 1

Are there limitations for getting data from YouTube?

Yes, see the quota usage section in Getting started.

One of the examples of what can be done per day might be helpful for your case:

if you have a daily quota of 1,000,000 units, your application could have [...] the following approximate limits:

• 200,000 read operations that each retrieve two resource parts.

Getting YouTube video comments

statistics.commentCount from Videos only gives you the amount.

commentThreads will give you the comments, see get_comments in the Python examples

Answer 2

CommentThreads

A commentThread resource contains information about a YouTube comment thread, which comprises a top-level comment and replies, if any exist, to that comment. A commentThread resource can represent comments about either a video or a channel.

HTTP request

GET https://www.googleapis.com/youtube/v3/comments

You might want to check CommentThreads: list, this will get all comment from Youtube video / channel.

Returns a list of comment threads that match the API request parameters.

You can check the code samples, it demonstrates how to use the following API methods to create and manage top-level comments.

Hope it helps!
