It is definitely 500 mA maximum if drawn from USB. I am not sure what the maximum total current draw is when using an AC to DC adapter.

Each pin can supply a maximum of 40-50 mA, depending on which board revision you have.

To be honest, if you find yourself needing to draw more than 500 mA, you should be using a separate power supply anyway.
