**Validation:**
```ruby
.is_valid(value)      # Main validation method
.valid?(value)        # Alias for is_valid
```

**Formatting:**
```ruby
.format(value)        # Format with standard symbols
.remove_symbols(value) # Remove formatting symbols
```

**Generation:**
```ruby
.generate             # Generate random valid value
```

### Utility-Specific Methods

**CEP:**
- `get_address(cep)` - Fetch address from CEP
- `get_cep_information_from_address(uf, city, street)` - Find CEPs

**Phone:**
- `is_valid(phone, type:)` - Validate with type (:mobile or :landline)
- `remove_international_dialing_code(phone)` - Remove +55/55

**License Plate:**
- `convert_to_mercosul(plate)` - Convert old format to Mercosul
- `get_format(plate)` - Detect format ("LLLNNNN" or "LLLNLNN")

**Voter ID:**
- `generate(uf)` - Generate for specific state

**Currency:**
- `format_currency(value)` - Format as R$ X.XXX,XX
- `number_to_text(value)` - Convert to Brazilian Portuguese text

**Date:**
- `is_holiday(date, uf)` - Check if date is holiday
- `convert_date_to_text(date)` - Convert to Portuguese text

**Legal Nature:**
- `get_description(code)` - Get description for code
- `list_by_category(category)` - List codes by category (1-5)

**Legal Process:**
- `generate(year, orgao)` - Generate for specific year and judicial segment

## 📊 Examples by Use Case

### Form Validation

```ruby
# Validate user input
cpf = params[:cpf]
if BrazilianUtils::CPFUtils.valid?(cpf)
  # Process valid CPF
else
  errors.add(:cpf, "inválido")
end
```

### Display Formatting

```ruby
# Format for display
cpf = "11144477735"
formatted = BrazilianUtils::CPFUtils.format_cpf(cpf)
puts formatted  # => "111.444.777-35"
```

### Test Data Generation

```ruby
# Generate test data
10.times do
  cpf = BrazilianUtils::CPFUtils.generate
  puts BrazilianUtils::CPFUtils.format_cpf(cpf)
end
```

### API Integration

```ruby
# Lookup address from CEP
address = BrazilianUtils::CEPUtils.get_address('01310100')
if address
  puts "#{address.logradouro}, #{address.bairro}"
