Need Phone Number Lookup Service API for Rails App

Does anyone know of a service that provides an API to look up phone
numbers by providing name, city, state, etc.? I would like to add this
information to a data collection app I am building in Rails. Nothing
along that line appears doing the usual Google search. Any info or
links would be appreciated.

Thanks,
Nathan
