TBH I think its a bit late to answer this question, But here it goes anyways.
All you need to do is format some JSON Data
Step 1:
Get the JSON
domain.com/wp-json/wp/v2/posts?per_page=1&_embed&taxonomy
Change per_page=1 to the number of posts you’d like to query
If you want to filter the post according to tags or categories
You can find more Query tags on:
http://v2.wp-api.org/reference/tags/
Step 2:
Format the JSON keep what you need forget the rest
Examples
Post Title & URL
Post Featured Image (It automatically gives you a link for thumbnails too)
Post Tags & Categories
