How can I scope and automatically buy low float items for CS2 on Steam community market?

I am trying to build a script that automatically looks for low float items on steam community market and if it was found for the specified amount make that purchase. I have seen some NPM packages for using steam but it wasn’t exactly what I was trying to do. If you have any ideas where to start and what can be done to achieve this please let me know.

I tried searching for some packages that would do similar things, but I couldn’t find any.
