Python CGI with API

I am quite new to python, I have built some applications in python with CGI and I found cgi is much easier compare to a framework as i have full control on everything. Tried to build a web api through below module but it end up with a web page rather than an api. Import cgi Import cgitb

I would like to create a web api, as I am familiar with cgi i would like to create it (web api) through python cgi,I have been looking for a good documentation but i dint find any. It would be helpful if someone can give me a clue. I really appreciate your help.
