Alternative way to fetch Potential stage history in a single api request?

Currently, we can fetch stage history of each potential by using "getRelatedRecords" methods, but it quickly consumed our api request limit and it about to reach maximum limit in just a single run.

Is there a way we can fetch all the stage history of an organization  by a single api request like using "getRecords" method?
