    I think the clue is in your comparison

    webClient.DownloadString(uri)

    to

    var response = await httpClient.GetAsync(uri);
return (await response.Content.ReadAsAsync());


    maybe you can try
    

    webclient.DownloadStringAsync(uri)

    

    and you could optimize your async code to
    

    await Task.Run(() => {
    // just run your sync code here
    var g1 = GetGizmos("url1");
    var g2 = GetGizmos("url2");
    var g3 = GetGizmos("url3");
    return Content("");
});

    

    It is enough to have one async yielding point here.
    

    Refer to this answer for details about async: Do you have to put Task.Run in a method to make it async?
