Designing with "real" data

In Interaction Design Uni i've got this assignment to design a prototype for an "Ebay for used books". A requirement is that we have use "real" Data and not lorem ipsum for our design prototype tools. Which is a fair point but....

It's about 50 book categories (crime, history, romance) we have to cover, and for every category the prof wants at least 2 Books.

I've don't have the time to type in the (meta)data for 100 books at 30 JSON properties by hand. What would be your advice?

Do you maybe know a easy to use online bookshop API? (remember I'm a tech savy designer not a dev)

Or do you know someone in a low income country who does data entry? Or any experience with hiring someone on fiverr?

Thank you for your help. :)
