How can I earn by running some scripts on my server?

Question

Automation

There is a wild desire to dive into the topic of automating any routine processes by running self-written scripts. Theoretically, I can write in python, php, js. Advise that this could be written so that it works itself and brings some kind of penny. There is absolutely no desire to engage in mining. I want to write some kind of script that would do something useful and so that later I could earn a little bit at the expense of it - even if it's 1 dollar a day.
Some kind of creators, checkers, parsers, etc. maybe there are some foreign services that pay for the work of scripts?

Answer 1

what could be written so that it works itself and brings some pretty penny

That doesn't happen.
Answer: no way.

Answer 2

I give an idea for a business;)
Parse aliexpress goods, sell the base or services based on it (if I understand correctly, there are mechanisms when you get a pretty penny from the seller for giving someone a link to them, while the prices for the goods are tied)
How make an adequate search option, aliexpress searches for goods so inadequately that you consider that they don’t have a search (I think specifically so that buyers for the worst offers are also found). There are not many such services and they are usually limited to certain categories of goods.
To do this, parse their database, it's not easy, because they resist, for example, their page in html takes 600kb, and almost all existing tools pass on its analysis (out of a thousand pages, a dozen can give a strange result) except probably the browser itself . The structure changes, the responses from the server change if it suspects scanning, etc.
