The bot that doesn't need a running PWI client?

Just wanted to ask if its possible to do that, and what is a mindset for creating one?

I know it's a bit too general, but still would be interested thankful for any peace of mind.

It's possible and has been done before. Just not public. I know several people who are currently writing things like this - I tried too but I never got beyond character listing, i'm too noob.
