react js – First API request, what are common places I should look into?

I’m not a web developer, neither very techie. But I manage to learn the basics of react for an idea I had before.

I want to display some data related to COVID. Is there any web you would recomment me for getting data, with an easy API interface? I don’t mind much what data do they provide, as long as it is a simple interface

Even if you don’t provide me a link, but some strategy to find simple APIs would be welcome. If you just googling like I’m doing now it would be good to know too, as I’m not sure about what approaches are common and what are not.
