How to use Options (blank: 0%fx) via API

I want to achieve below result via API. I know this can be done via the schema page, Options blank: 0%fx, is this something can be return in API? Please advise. Thank you.

For example: input - Oct/2020, 120

Out put:
Date, Incident#

02-Oct-2020, 130
03-Oct-2020, 100
