    You need to get the HLS m3u8 playlist files from the video's manifest. There are ways to do this by hand, but for simplicity I'll be using the youtube-dl tool to get this information. I'll be using this live stream as an example: https://www.youtube.com/watch?v=_Gtc-GtLlTk

    First, get the formats of the video:

    ➜  ~ youtube-dl --list-formats https://www.youtube.com/watch\?v\=_Gtc-GtLlTk

    In this case, there are two videos because the live stream contains two cameras. From here, we need to get the HLS URL for a specific stream. Use -f to pass in the format you would like to watch, and -g to get that stream's URL:

    These are your HLS m3u8 playlists, one for each camera associated with the live stream.

    Without youtube-dl, your flow might look like this:

    Take your video id and make a GET request to the get_video_info endpoint:

    HTTP GET: https://www.youtube.com/get_video_info?&video_id=_Gtc-GtLlTk&el=info&ps=default&eurl=&gl=US&hl=en
    

    In the response, the hlsvp value will be the link to the m3u8 HLS playlist:

    Yes this is possible Since the question is update, this solution can only gives you the embed url not the HLS url, check @JAL answer. with the ressource search.list and the parameters:

    * part: id
    * channelId: UCURGpU4lj3dat246rysrWsw
    * eventType: live
    * type: video
    

    Request :

    GET https://www.googleapis.com/youtube/v3/search?part=snippet&channelId=UCURGpU4lj3dat246rysrWsw&eventType=live&type=video&key={YOUR_API_KEY}
    

    Result:

     "items": [
      {
       "kind": "youtube#searchResult",
       "etag": "\"DsOZ7qVJA4mxdTxZeNzis6uE6ck/enc3-yCp8APGcoiU_KH-mSKr4Yo\"",
       "id": {
        "kind": "youtube#video",
        "videoId": "WVZpCdHq3Qg"
       }
      },
    

    Then get the videoID value WVZpCdHq3Qg for example and add the value to this url:

    https://www.youtube.com/embed/ + videoID
    https://www.youtube.com/watch?v= + videoID
