API Design for particular use-case

I've to design APIs, with MongoDB being used as storage.
Will be using Node/ExpressJS for now.

So ... here's my use case.
There would be a lot of attributes/fields in each MongoDB document (more than 20)
But anytime I'd fetch the document, I'd only want 2-3 fields ... based on arguments
Also, there'll be filters passed on to the back-end
Seems like a perfect use case for GraphQL

But the problem is that only a few attributes (~5-6) would be known beforehand.
