You go here https://console.cloud.google.com/apis/api/youtube.googleapis.com/credentials then afterwards you click on create credentials then go to API Key then you can copy your api key, email it to yourself and then insert it into the TubeFixer settings More on reddit.com

Is there any way to check if the quota for the ZP YouTube API key has been exceeded before (or after) the player starts? Are you planning to create a corresponding function? More on reddit.com

Here's an example function I wrote in Python which grabs all of the videos in a playlist, given the api key and playlist id: def get_playlist(playlist, api_key): # Set up the url base = 'https://www.googleapis.com/youtube/v3/playlistItems' key = f'key={api_key}' playlist_id = f'playlistId={playlist["id"]}' videos = [] def fetch_page(url): # GET the url. We'll ignore the error since this is a pet thing r = requests.get(url) raw_data = json.loads(r.text) # Refine the video list for raw in raw_data['items']: if raw['snippet']['title'] != 'Private video': videos.append(extract_video_data(raw, playlist['name'])) # If there are 50+ videos in the list, we'll also need to know how to get the next page return raw_data.get('nextPageToken') next_page_token = fetch_page(f'{base}?{key}&{playlist_id}&part=snippet&maxResults=50') # Repeat the above while there are more pages to process while next_page_token: next_page_token = fetch_page(f'{base}?{key}&{playlist_id}&part=snippet&maxResults=50&pageToken={next_page_token}') return videos To most directly answer your question, you authenticate to the API by passing your key as an argument in your request. There's probably more elegant ways to do this, but it's easily accomplished by literally appending the key-value pair key= after the ? in the URL More on reddit.com

I don't know much about youtube api, but 10,000 requests per day is to much. Maybe you coded something that triggered infinite requests by accident and you didn't realize. That would be my only guess. More on reddit.com
