import org.wickra.screener.Screener;

public final class Scan {
    public static void main(String[] args) {
        String spec = """
            {"universe":["AAA","BBB"],
             "condition":{"type":"cmp",
               "left":{"kind":"indicator","name":"Rsi","params":[14]},
               "op":"lt","right":{"kind":"const","value":30.0}}}""";

        try (Screener screener = new Screener(spec)) {
            String response = screener.command("{\"cmd\":\"scan\",\"data\":{}}");
            System.out.println("wickra-screener " + Screener.version());
            System.out.println(response);
        }
    }
}

The binding uses the Java Foreign Function & Memory API, so it needs JDK 22+ and --enable-native-access.
