    private readonly IDaDataSuggestionsClient _client;
    
    public AddressesController(IDaDataSuggestionsClient client)
    {
        _client = client;
    }

    /// <summary>
    /// Suggests addresses for the specified query.
    /// </summary>
    [HttpGet("suggestions")]
    public Task<IReadOnlyList<AddressSuggestion>> GetSuggestionsAsync(string query) => _client.SuggestAddressAsync(query);
    
    /// <summary>
    /// Suggests cities for the specified query.
    /// </summary>
    [HttpGet("cities")]
    public async Task<IReadOnlyList<AddressSuggestion>> GetCitiesAsync(string query)
    {
        var request = SuggestAddressRequest.Create(query).From(SuggestAddressBound.City).To(SuggestAddressBound.City);
        var response = await _client.SuggestAddressAsync(request);
        
        return response.Suggestions;
    }
}
