Map Api port in an MVC project

I created an MVC project and within an API.

I need to get the API when I upload the project to (F5).

Example, I created a service that is a GET in my Type table.

How can I map the API to be able to get inside an MVC controller?

My project is Asp.Net MVC and inside it I have a Web API project, the services are in the Web API and by MVC I should get the service and fill in some Views.

This method works inside the API service, but now with MVC I do not know how to call.

public class GetCidades
    {
        BancoContext banco = new BancoContext();

        public List<Cidade> getCidades()
        {
            var result = banco.Database.SqlQuery<Cidade>("sp_cons_cidade").ToList();

            return result;
        }
    }

How do I get this service inside the MVC. I did this

public class GetCidades
    {
        HttpClient client = new HttpClient();
        List<Cidade> cidades = new List<Cidade>();

        public async Task<List<Cidade>> GetCidadesAsync()
        {
            string url = $"http://localhost:51381/api/";
            var response = await client.GetStringAsync(url);
            var _cidade = JsonConvert.DeserializeObject<List<Cidade>>(response);
            return _cidade;
        }
    }

But I do not know what else to do.

Do I need to map anything? Because when I give F5 up the two, right, MVC and API and from within the MVC how do I get the API?

EDIT1

My controller within the MVC

public class GetCidadeController : Controller
    {
        // GET: GetCidade
        public ActionResult Index()
        {
            return View();
        }

        public ActionResult GetCidades()
        {

            return View();
        }
    }

The API controller

[RoutePrefix("api/[controller]")]
    public class GetCidadesController : ApiController
    {
        GetCidades cidades = new GetCidades();

        [AcceptVerbs("Get")]
        public IEnumerable<Cidade> getCidades()
        {
            return cidades.getCidades().AsEnumerable().ToList();
        }

    }

Lost. I do not know if this is how it should be done
