How do I operate around Stack Exchange API in .NET Core MVC

How can do I work with StackOverflow API and HTTP request it?

This is my problem: I want to get first 1000 tags from Stack Exchange API, see their popularity and usage.

This is what I've done so far:

1. Created an ASP.NET MVC project

2. Added HTTP Client in Startup.cs file:

    public void ConfigureServices(IServiceCollection services)
    {
        services.AddControllersWithViews();
        services.AddHttpClient("stackoverflow", s =>
        {
            s.BaseAddress = new Uri("https://api.stackexchange.com/2.3");
            s.DefaultRequestHeaders.Add("client_id", "1");
            s.DefaultRequestHeaders.Add("site", "stackoverflow");
            s.DefaultRequestHeaders.Add("redirect_uri", "https://api.stackexchange.com/2.3/tags?");
        });
    }
   

3. Created classes Tags and interface ITagsRepository:

    public class Tags
    {
        public int Id { get; set; }
        public int Popularity { get; set; }
        public decimal Usage { get; set; }
    }
   
    public class TagsRepository : ITagsRepository
    {
        public Tags GetTag(int id)
        {
            // put logic in here
        }
    }
   

4. I also have added a TagsController in HomeController.cs:

    public class TagsController : Tags
    {
        private ITagsRepository _tagsRepository;
   
        public TagsController(ITagsRepository tagsRepository)
        {
            _tagsRepository = tagsRepository;
        }
   
        public IActionResult GetTag(int id)
        {
            Tags tag = _tagsRepository.GetTag(id);
            return View(tag);
        }
    }
   

My question is: how do I make my code run in index.cshtml and how do I make http requests that are customisable from client side?
