I found an API that returns the proxy type, But I ratherd this to be localized rather than an api call.

I cant even write a checker or anything near. I just know the simple basics.

We all gotta start somewhere, heres an example of a multi-threaded checker https://cracked.to/Thread-C-Source-Fast-...cc-checker

At first you should ask how its avoided to detect a proxy to later try to find out programmatically.

To detect a proxy there are more possibilities.
One mayor detection is based on the request headers sent from the proxy.
This means that e.g. the "via" and the "forwarded" and "follow_x.." headers should be deactivated.
E.g. if you configure it as a transparent, it passes your (another) IP to the server.

Then there are blacklists who filter datacenters. So if you rent a cheap datacenter vps, install a squid proxy, you maybe still marked as proxy. This is why there are sold many "residental" proxies coming from ISP ranges.

So if you want to detect via C# you should consider to filter by request headers.
(The attempt would be to do a request and catch the request, analyse/filter headers via C#)

This is a good page to get information about your using proxy.

Hope I could help a bit.

Code:

 
public static bool Validity; public static string type; public static void ValidateProxy(string proxy)
{

JObject jobject = JObject.Parse(new WebClient().DownloadString("http://ip-api.com/json/" + proxy.Split(':')[0])); ;
string country = (string)jobject["regionName"]; string validity = (string)jobject["status"];
if (validity.Contains("success")) { Validity = true; }
else { Validity = false; }
            var client = new HttpRequest();
            for (int i = 0; i <= 3; i++)
            {

                client.UserAgent = "Mozilla/5.0 " +
                "(Windows NT 10.0; Win64; x64) " +
                "AppleWebKit/537.36 " +
                "(KHTML, like Gecko) " +
                "Chrome/58.0.3029.110 " +
                "Safari/537.36 " +
                "Edge/16.16299";
                switch (i)
                {
                    case 0:
                        client.Proxy = HttpProxyClient.Parse(proxy);
                        type = "Http";
                        break;
                    case 1:
                        client.Proxy = Socks4ProxyClient.Parse(proxy);
                        type = "Socks4";
                        break;
                    case 2:
                        client.Proxy = Socks4AProxyClient.Parse(proxy);
                        type = "Socks4A";
                        break;
                    case 3:
                        client.Proxy = Socks5ProxyClient.Parse(proxy);
                        type = "Socks5";
                        break;
                }

                Console.WriteLine(type);

                client.IgnoreProtocolErrors = true;
                client.AllowAutoRedirect = false;
                client.KeepAlive = true;
                client.ConnectTimeout = 200;
                try
                {
                    string URL = @"https://www.google.com/";
                    string response = client.Get(URL).ToString();                    
                    i = 3;
                }
                catch { }
            }
            

}
