Intergrate an api

I need someone that understand [login to view URL] and to use my key I have to make it work [login to view URL] which is a wordpress site. I need it so that the data for the buisness autopops but I want to be able to add data such as discriptions and such to the info. Alot like yelp or other sites do. I have all the really hard stuff already done I just need somone that reads and knows api coding to get it into my site asap.
