Duolingo supports 40+ languages including English, Spanish, French, German, Italian, Portuguese, Japanese, Korean, Chinese, Hindi and many more. Use get_version_info to see the full list of supported language codes.

The public API returns limited profile data. For full progress including individual skill levels and detailed stats, you need to be authenticated with your Duolingo session. The username-based endpoint returns basic info like total XP, streak and current language.
