Feature Request

So that even inexperienced programmers can query the country of a player and then set the flag for it in a simplified manner.

Example Use-Case

public static String getCountryCode(String ip) {
        String apiUrl = "http://ip-api.com/json/" + ip;
        try {
            URL url = new URL(apiUrl);
            HttpURLConnection conn = (HttpURLConnection) url.openConnection();
            conn.setRequestMethod("GET");

            BufferedReader reader = new BufferedReader(new InputStreamReader(conn.getInputStream()));
            Map<String, Object> json = new Gson().fromJson(reader, Map.class);
            reader.close();

            return json.containsKey("countryCode") ? (String) json.get("countryCode") : "Unknown";

        } catch (Exception e) {
            e.printStackTrace();
            return "Error";
        }
    }
