YouTube API v2 allows you to a) search for safeSearch only and b) get the media rating (eg PG-13) <https://developers.google.com/youtube/2.0/reference#youtube_data_api_tag_media:rating> .

Is there a way to do this in the v3 API?

If not: Why was this omitted? Are there plans to remove it from v2?

In general, what's the best way using the API to tell if a video is safe?
