Your web API will be an URL: www.myapi.com/api.aspx?

Your api.aspx will have the code I provided.

Or you just don't how do it?

May you need something like this:

using HtmlAgilityPack;
using Fizzler.Systems.HtmlAgilityPack;

//get the page
var web = new HtmlWeb();
var document = web.Load("http://example.com/page.html");
var page = document.DocumentNode;

//loop through all div tags with item css class
foreach(var item in page.QuerySelectorAll("div.item"))
{
    var title = item.QuerySelector("h3:not(.share)").InnerText;
    var date = DateTime.Parse(item.QuerySelector("span:eq(2)").InnerText);
    var description = item.QuerySelector("span:has(b)").InnerHtml;
}
