How much can i earn from selling APIs?

I’m a collage student learning python and i watched Anía Kubów’s video on selling APIs, so i thought it would be a nice way to earn some money on the side without it taking up to much of my study time. I was planing to use flask or django for making APIs, and i was wondering does anyone have any experience with this and can you earn some decent money doing this (by decent i mean not too much, just something to help me get by). And if not does anyone have an idea about some other way for me to earn money from programming without it taking up too much of my time. Thank you.

Hi, I feel like you should adress that question to the person who’s video you saw.
Like, there in the comments or if there is a community like Discord or so.
