Other than incorporating Adsense. Has anybody seen or thought of a way to use the Google API to make money?

Umm, I am not sure, is there a possible way ?? I havent ever seen one

I dont think there are any other way.. I dont recommend using them in other ways than they are used now since most likely if there really are other ways, it will be something that google wont like and enetually, they might ban you...

Yeah same with the other two posters I am pretty sure there aren't any other ways than using adsense.
