Thanks, Dominique, I was inattentive. But problem still not solved. Not I 
have an error

Global symbol "$json" requires explicit package name


at string marked yellow.

api_func1(sub => {
 my ($self, $json) = @_;
 $c->render(json => $json);
})

What could be wrong?

Also tried 

api_func1(sub => {
 *my $json = shift;*
 $c->render(json => $json);
})

But same error.
