ok if this is not an API Then against what I need to launch the code?
First, find out what type of wallet you are trying to brute force if you haven't already. I have a suspicion that you are not so sure exactly what type of wallet you have.
Once you find the wallet format, see if it has a Python package that can programmatically open & read it, and then build a script around that (potentially using ChatGPT if it is one of the more well known packages, but you should at least make an effort to learn just enough Python to write one yourself).
