Hello frns, Can anybody tell me about what is API and API key? plz give me some information about API and how to use it. Thanx.
Application Programming Interface http://en.wikipedia.org/wiki/API In short, you can write programs that pull information from other data sources. But I assume you are asking about Google's API. They assign you a key code that verifies you when your program tries to get data. Loads of info here on all the different stuff you can access from Google: http://code.google.com/apis/
