无法正确获取JSON数据

我正在尝试从此服务https://coinmarketcap.com/api/获取加密数据，而Postman返回以下响应正文：

            }
        }
    },

这是我的JSON结构。我收到以下错误。有什么事吗

valueNotFound（Swift.Double，Swift.DecodingError.Context（codingPath：[CodingKeys（stringValue：“ data”，intValue：nil），CodingKeys（stringValue：“ quote”，intValue：nil）

struct Response: Decodable {

我要提出的功能：

func loadData() {
    
    guard let url = URL(string: "https://pro-api.coinmarketcap.com/v1/cryptocurrency/listings/latest") else {
        
        print("Wrong URL.")
        return
    }
    
    let finalURL = url
    var request = URLRequest(url: finalURL)
    request.addValue("c972ac08-519e-47e5-8cd8-23e6230289f3", forHTTPHeaderField: "X-CMC_PRO_API_KEY")
    
    let dataTask = URLSession.shared.dataTask(with: request) { (data, responce, error) in
        
        if let jsonData = data {
            
            do {
                
                let cryptoData = try JSONDecoder().decode(Response.self, from: jsonData)
                print(cryptoData)
            }
            
            catch {
                
                print(error)
            }
        }
    }
    dataTask.resume()
}
