Do you need a database with tasks in higher mathematics and / or other disciplines?

Question

API

I want to make a bot according to the type:
1) a person chooses a discipline
2) a bot sends a task/example from the database via api text/picture
3) a person sends an answer
4) a bot makes a request to the database, compares the answers and displays true/false
I don’t want to parse. But in general, I will consider all the proposed solutions with pleasure.
