Social Exchange Module NEEDED

Simple, I have a client that needs someone to reverse engineer something to create a module that creates followers for exchange. Details are in the zip file below with examples of the script and module. I looked at the code myself only thing I do not know is how to connect the API to the site so that the site can tell if that user followed that person they followed to. I can give a few of the modules for example. Like I said, the API part is the part that needs to come back. Also, the SQL I can import in their database. I will also add a example of the database input file.
