Does anybody have some sample code that shows how to get the daily, total billed cost (across all campaigns) of a google ads account?

I have been looking for a sample for a while but could not find where you can get the total cost/billed cost for the day (or for a certain period of time).

I am doing this in Js but a sample in any language is okay. I would like to send this data to an airtable base, so if you have any suggestions on how that can be done too, that would be great!

Thanks in advance!
