How do I specify a parameter in the URL?

http://api.stackoverflow.com/0.8/questions works as expected.

Then I would like to pass parameter *body* with a value of *true* (that is available according to the [documentation for /questions][1]).

I have tried:

    http://api.stackoverflow.com/0.8/questions/body{true}


and

    http://api.stackoverflow.com/0.8/questions/body(true)
