Then check below link for API (i.e, SITE_URL/wp-json/wp/v2/posts ) You will get list of posts which are added in website http://itechnotion.in/wp-news/wp-json/wp/v2/posts
There is list of APIs for getting different types of data (i.e, posts, categories, comments, etc.) That list I have attached at end of this document.
If there is need to add extra fields which aren’t providing by default API, then you need to add custom function for adding extra fields in below file /wp-content/themes/themename/functions.php I have added some custom functions there for adding extra needed fields.
And for contact_us form & add comment form, I have written two APIs there in /api folder.

SITE_URL/wp-json/wp/v2/posts/ or
SITE_URL/wp-json/wp/v2/posts/?page=1
