GraphQL as a unification layer for multiple REST sports APIs?

I’m building SportsFlux , a live sports dashboard that consolidates different leagues in real time into one interface, eliminating the need to jump between platforms to follow games. it also reduces clutter and the annoying popups

Since external providers mostly use REST with inconsistent schemas, I’m considering GraphQL internally to standardize the client-facing data.

Has anyone used GraphQL primarily as an aggregation layer?

for context, this is my progress so far https://sportsflux.live⁠
