# Brazil::Cep

This gem provides a simple way to validate and format Brazilian postal codes (CEP).

## Installation

`$ gem install brazil-cep`

Or add this line to your application's Gemfile:

```ruby
gem 'brazil-cep'
```

## Usage

### Fetching address by CEP using default provider

```ruby
address = Brazil::Cep.fetch('01311-200')
address.street # => "Avenida Paulista"
address.neighborhood # => "Bela Vista"
```

### Fetching address by CEP using custom provider

```ruby
address = Brazil::Cep.fetch('01311-200', provider: :postmon)
address.street # => "Avenida Paulista"
address.neighborhood # => "Bela Vista"
```

### Creating a custom provider adapter

```ruby
module Brazil
  module Cep
    module Adapters
      class MyProvider < Base
        provider base_url: 'https://api.myprovider.com/address/{{cep}}'

        private

        def transformation!
          address_params = {
            street: response[:street],
            neighborhood: response[:neighborhood],
            ...
          }
          
          Brazil::Cep::Address.new(**address_params)
      end
    end
  end
end
```
