How to request all columns possible by API?

I am currently developping 3 jobs that get some columns for a single website_id (events and query mode).
I wonder if it is possible to get all columns in one call for a single scope ? I cant find solution on API doc.
I would like to standardize my job so i can loop on every website, i dont know if it is possible.
Any tips ?

All columns of the database?

I would say yes, but im not sure, im new on this API…
I mean all columns such as source_medium, custom_event_name, custom_event_action, custom_event_category, event_url…

What i mean by “scope” is event scope


Here some documentation:
