Quota exceeded for quota metric 'Requests' and limit 'Requests per minute' of service 'mybusinessaccountmanagement.googleapis.com'

I get this error after making my first request:

Quota exceeded for quota metric 'Requests' and limit 'Requests per minute' of service 'mybusinessaccountmanagement.googleapis.com'

How can I be over my quota after my first request?

if(File.Exists(ApplicationVariables.CertPath)) { 
                    GoogleCredential credential;
                    using (var stream = new FileStream(ApplicationVariables.CertPath, FileMode.Open, FileAccess.Read))
                    {
                        credential = GoogleCredential.FromStream(stream).CreateScoped("https://www.googleapis.com/auth/business.manage");
                    }

                    // Create the service.
                    var service = new MyBusinessAccountManagementService(new BaseClientService.Initializer()
                        {
                            HttpClientInitializer = credential,
                            ApplicationName = "Google Reviews Downloader",
                        });

                    //var bookshelves = await service.Mylibrary.Bookshelves.List().ExecuteAsync();
                    var accounts = await service.Accounts.List().ExecuteAsync();

                    Console.WriteLine("accounts:" + accounts);

                }

That would depend entirely on how much quota you have currently.

When you enable the My Business Account Management API in Google developer console. THe default quota is 0

I would suggest that you try and add additional quota.

Your going to have to click the quota page link and dig around in there a while until you figure out how to increase the quota, they changed it recently, you may have to apply for quota im not sure with this api.

I have tried and im not any wiser as to how to request quota or increase the quota. I wonder if this is one of the APIs that you need special permission to access. How you get that permission im not sure but im going to do a bit of digging.
