Where can I get an API to make a client for it?

Question

API

Sobsno, it's understandable.
I am mastering Angular and I want to make a face for some API.
At a minimum, the display of information. Ideally, full CRUD if allowed.
Does anyone have anything in mind?
The topic is not important (weather / finance / schedules, etc.)
Thank you

Do it yourself.
Make the simplest tables in the database, for example, Author-Genre-Books or Movie Library (Director-Genre-Film-Actors)
Connect to it, form json and return it.
I would install django and django-rest-framework, the simplest api with a sqlite3 base can be configured according to the manuals in 10 minutes.
