title: How to get wordpress api data by language?
body: <p>Let's say I have this api <a href="http://someUrlHere.com/wp-json/wp/v2/posts?categories=19&amp;per_page=20" rel="nofollow noreferrer">http://someUrlHere.com/wp-json/wp/v2/posts?categories=19&amp;per_page=20</a>
  and I call it with GET method.
  How can I choose what language I want to receive the information? It should pe provided in 2 languages. Or how do I find out if it is provided only in English?</p>
