While Lee's solution works for me, it would be nice if Dancer would let 
me restrict the automatic serializer to a route prefix:

     serializer:
         format: JSON
         prefix: /api

That would entirely replace Lee's solution.

This wouldn't break backwards compatibility.  If you give 'serializer' a 
scalar, it can use its current global behavior.

Passing an array of hashes instead of a hash could allow different 
serializers for different parts of your route scheme:

     serializer:
         - format: JSON
           prefix: /api

         - format: Data::Dumper
           prefix: /debug
