Get whole dataset via API

I want to save the whole dataset as pandas DataFrame in Python, I know I can do this when I download the whole dataset but I would like to get it directly via API without downloading the file. Is that possible?

I don’t have the answer, but I do want to extend the question.
Using api’s, how can I get the diff data? The data from the csv file wich represents the alterations in cell network from one day to another (OCID-diff-cell-export-2021-03-26-T000000.csv).
