Formating content rendered from wordpress REST API as JSON and not HTML

I am new to WordPress and REST API and I need to read posts from /wp-json/wp/v2/posts with an external application called Intuiface.

Intuiface can interpret JSON but the content of the post is shown in html:

    "<p>Content</p>"

Is it possible for wordpress to format this as text and image links if there are images instead of HTML?
