Licence
ViaCEP publishes no terms of use, licence or attribution requirement on its site. The service is free and keyless but grants no rights over the address data, which originates from the Brazilian postal service (Correios). No reuse licence is stated anywhere on the service's site or API documentation. Access is offered free of charge but no grant of rights accompanies it; we therefore claim nothing: commercial use and redistribution are both recorded as false and the response is passed through unmodified and uncredited as ours.
