Problems when searching for zip code from another country

Question

I have the following code that when I type the postal code it returns with the data of my country, but I would like to do a search using the postal code of other countries. How can I adapt my structure to my code?

public ActionResult Pesquisar(string zipCode)
{

        string key = ConfigurationManager.AppSettings.Get("keyAPIGoogleCloudServices");
        ReplyZipCodeGoogle ReplyZipCodeGoogle = null;
        using (var client = new HttpClient())
        {
            client.BaseAddress = new Uri("https://maps.google.com/maps/api/geocode/");
            //HTTP GET
            var parameters = "&sensor=false&languague=pt-BR&region=br";
            var key = "&key=" + key;
            var research = "json?address=" + zipCode;
            ServicePointManager.SecurityProtocol = (SecurityProtocolType)3170;
            //var responseTask = client.GetAsync("json?address=29102-100&sensor=false&languague=pt-BR&region=br&key=AIzaSyDPFP6WqSoSiECqAJqE1P3kVkueJAujVtQ");
            var responseTask = client.GetAsync(pesquisa + parameters + key);
            responseTask.Wait();

            var result = responseTask.Result;
            if (result.IsSuccessStatusCode)
            {
                var readTask = result.Content.ReadAsAsync<ReplyZipCodeGoogle>();
                readTask.Wait();
                ReplyZipCodeGoogle = readTask.Result;

            }
            else //web api sent error response 
            {

            }
        }
        if(RespostaCepGoogle.Status == "ZERO_RESULTS")
            throw new CoreException("Zip code does not exist. Please enter a valid zip code.");

}

How can I adapt a way to get the zip code from Paraguay, for example?

Since I don't know which nuget package you are using, I cannot reproduce your problem now.

But according to your description, I wrote some code using bing map API, please try to see if it can meet your needs.

       static async Task Main(string[] args)  
        {  
            string zipCode = "99999";  
           await Pesquisar(zipCode);  
            Console.WriteLine("Press any key to continue......");  
            Console.ReadLine();  
        }  
        public static async Task Pesquisar(string zipCode)  
        {  
            HttpClient httpClient = new HttpClient();  
  
            // get key from https://www.microsoft.com/en-us/maps/create-a-bing-maps-key#basic   
            string mapKey = @"your map key";  
            try  
            {  
                string path = String.Format(@"http://dev.virtualearth.net/REST/v1/Locations?postalCode={0}&key={1}", zipCode, mapKey);  
                HttpResponseMessage response = await httpClient.GetAsync(path);  
                response.EnsureSuccessStatusCode();  
                string responseBody = await response.Content.ReadAsStringAsync();  
  
                Console.WriteLine(responseBody);  
            }  
            catch (HttpRequestException e)  
            {  
                Console.WriteLine("\nException Caught!");  
                Console.WriteLine("Message :{0} ", e.Message);  
            }  
        }
