Answer 1

Your API should have 2 ports binded and then Swagger will be displayed for both with no extra configuration... Example using .NET Core:

launchSettings.json:

"applicationUrl": "https://localhost:5001;http://localhost:5000"

Program.cs:

public class Program
{
    public static void Main(string[] args)
    {
        CreateHostBuilder(args).Build().Run();
    }

    public static IHostBuilder CreateHostBuilder(string[] args) =>
        Host.CreateDefaultBuilder(args)
            .ConfigureWebHostDefaults(webBuilder =>
            {
                webBuilder.UseStartup<Startup>();
            });
}

and in Startup.cs

-ConfigureServices method:

services.AddSwaggerGen(c =>
{
    c.SwaggerDoc("v1", new OpenApiInfo { Title = "NameOfAPI", Version = "v1" });
});

-Configure method:

app.UseSwaggerUI(c =>
{
    c.SwaggerEndpoint("/swagger/v1/swagger.json", "NameOfAPI");
    c.RoutePrefix = string.Empty;
});
