Have you considered using Chained for this?  Your URL structure looks like
it would lend itself nicely to that.

You'd do something like:

package MyApp::Web::Controller::API::REST::Documents;
use ...
BEGIN { extends 'MyApp::Web::Controller::API::REST' }

# chaining to '.' allows you to have a chain root in a parent class
# that you can chain off of and inherit functionality from (see
http://search.cpan.org/~bobtfish/Catalyst-Runtime-5.80032/lib/Catalyst/Disp=
atchType/Chained.pm#Attributesunder
"Chained")
# also, specify the path part here, so index acts how you want it to as an
end point.
sub documents : Chained('.') PathPart('documents') CaptureArgs(0) {
  my ($self, $c) =3D @_;
  # do whatever document grabbing functionality you need to do here
}

sub index : Chained('documents') PathPart('') Args(0) {
  my ($self, $c) =3D @_;
  # display stuff etc
}

NOTE: This is untested code, but it SHOULD give you an idea of what to do.
