I got to this thread when trying to do the same today. Although this is way late, but the answer is YES, there is actually simple API key for those apis that does not need user authorizations, and the official client library support this.

The api library do this by Options, which is key, value pair.

Take the example of get information of a given youtube video, you would use this api: https://godoc.org/google.golang.org/api/youtube/v3#VideosListCall.Do

To use api key, simply make a type that implements the CallOption interface, and let it return the api key:

type APIKey struct {
}

func (k *APIKey) Get() (string, string) {
    return "key", "YOU API KEY HERE"
}

Then when calling the API, supply the APIKey to it:

youtube, err := youtube.New(&http.Client{})
call := youtube.Videos.List("snippet,contentDetails,statistics").Id(id)
rsp, err := call.Do(opt)

This way, you can construct the youtube client with the vallina http client, rather than oauth client, and enjoy the simple api key.

The first answer said you can use http GET directly, but then you will need to handle the errors and parse the result yourself.
