        curses.start_color()
        curses.init_pair(1, curses.COLOR_GREEN, curses.COLOR_BLACK)
        curses.init_pair(2, curses.COLOR_RED, curses.COLOR_BLACK)
        curses.init_pair(3, curses.COLOR_YELLOW, curses.COLOR_BLACK)

        try:
            whileTrue:
                resp = get_data()
                report_progress(get_data())
                time.sleep(60/REQUESTS_PER_MINUTE)
        finally:
            curses.echo()
            curses.nocbreak()
            curses.endwin()
