To make ANY YouTube Data API v3 request WITHOUT ANY KEY/USING YOUR QUOTA, you can use: https://yt.lemnoslife.com/noKey/YOUR_REQUEST
For instance you can use: https://yt.lemnoslife.com/noKey/videos?part=snippet&id=VIDEO_ID instead of https://www.googleapis.com/youtube/v3/videos?part=snippet&id=VIDEO_ID
I may add in the future limitation per IP etc if the quota need to be better shared among the persons using this API.
Currently this service is powered by 10 keys.
