This is pretty sweet! Specially it being free. I just added support for Libre Translate to my Javascript translation library, `translate` [1]:

    import translate from 'translate';
    translate.engine = 'libre';

    const text = await translate('Hello world', 'es');

Please let me know in an issue if you start charging for it at some point so I can point out how to get a key and everything!

> Note: it takes few minutes to show on npmjs.com, but if you do `npm info translate` you can see how the new version has been published.
