I am using WordPress API to show post in app. How can i get custom or filtered endpoints in WordPress API? I want only following things,

• Post title
• Post content
• Post Date
• Post categories
• Post featured image
• Author Name, bio and image.

rest every thing in the API should be omitted or should create a new API URL. Is there any plugin I can use to do so? I am not very good in php. Thank you.
