http://fabrik42.github.io/acts_as_api/#section-What_can_I_include_in_my_responses?

link: _Include attributes and all other kinds of methods of your model_
and link: _Call methods of a parent association_
both reference to https://github.com/fabrik42/acts_as_api/wiki/Calling-a-method-of-the-model

I think its a mistake.
