How to program API...go from where ?

[hentaiw]

I gotta design an API to serve some tool that could help me best...I use API from a website...but since I got basic C++ where should I go to before API ? Could you please suggest some subject that needed to train before making API-using tools.

I'm not sure I fully understand your request but look at:

API Design for C++
by Martin Reddy
http://www.amazon.co.uk/API-Design-C-Martin-Reddy/dp/0123850037

even if you don't buy the book a good look at the contents page via the 'look inside' feature should suggest some subject areas to get familiar with.
