This webapi project is cosuming Brasil API - https://brasilapi.com.br/api/ - to get CEP code details.

HTTP Client Wrapper and Flur will show the same result.

HTTP generic client wrapper

Generic HTTP wrapper to consume RESTful API.

AddressController.cs

       [HttpGet("cep-details/http-client-wrapper/{cep:int}")]
        public async Task<IActionResult> GetAddressDetailsByCepUsingHttpClientWrapper(int cep)
        {
            return Ok(await HttpClientWrapper<AddressViewModel>.Get(_urlBrasilApi + $"cep/v1/{cep}"));
        }

Result

{
"cep": "89010025",
"state": "SC",
"city": "Blumenau",
"neighborhood": "Centro",
"street": "Rua Doutor Luiz de Freitas Melro",
"service": "viacep"
}

HttpClientWrapper.cs

        public static async Task<T> Get(string url)
        {
            T result = null;
            using (var httpClient = new HttpClient())
            {
                var response = httpClient.GetAsync(new Uri(url)).Result;

                if (!response.IsSuccessStatusCode)
                {
                    throw new Exception(await response.Content.ReadAsStringAsync());
                }

                await response.Content.ReadAsStringAsync().ContinueWith((Task<string> x) =>
                {
                    if (x.IsFaulted)
                        throw x.Exception;

                    result = JsonConvert.DeserializeObject<T>(x.Result);
                });
            }

            return result;
        }

Flur

Flurl is a modern, fluent, asynchronous, testable, portable, buzzword-laden URL builder and HTTP client library for .NET.

AddressController.cs

        [HttpGet("cep-details/flur/{cep:int}")]
        public async Task<IActionResult> GetAddressDetailsByCepUsingFlur(int cep)
        {
            return Ok(await _urlBrasilApi.AppendPathSegment("cep/v1/" + cep).GetJsonAsync<AddressViewModel>());
        }
