I finished the quotes application a few days ago, but I have noticed many campers struggling with an API, so I made mine public.
You should either get all the quotations from:
Or get a quotation by its ID at https://mysterious-sierra-49778.herokuapp.com/api/quotations/ID where ID is an integer between 1 and 10 (there are only 10 quotes in the database).
The API returns JSON, and only accepts GET requests.
The code is at https://github.com/Oxyrus/Wonka
Hope this makes your project easier to accomplish
