// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

Chilkat.Http http = new Chilkat.Http();

http.Login = "ACCESS_TOKEN";
http.Password = "";
http.Accept = "application/json";

// Lookup an IPv4 address: 149.250.207.170  (this was a randomly chosen address)
string jsonStr = http.QuickGetStr("https://ipinfo.io/149.250.207.170");
if (http.LastMethodSuccess == false) {
    Debug.WriteLine(http.LastErrorText);
    return;
}

Chilkat.JsonObject json = new Chilkat.JsonObject();
json.EmitCompact = false;
bool success = json.Load(jsonStr);

Debug.WriteLine(json.Emit());
