@Shreyanand Can you fix the pre-commit errors? Otherwise LGTM :+1:

[4n4nd]

Also, there is a notebook in the api client project repo which is similar to this one. Should we add the MetricRange and MetricSnapshot content there as well?

Sure! E402 module level import not at top of file what is this expecting? Do imports need to be on the first line of the cell? Or before markdowns?

@Shreyanand looks great! Left a small suggestion :)

For transparency: Checked it locally, turns out that you can't put anything before import statements. Not even !pip install commands.
