行情数据api可以快速获取实时tick数据信息，也即所谓的逐笔成交价格。市面上稳定可用的贵金属行情接口虽然比股票的要少，但好产品还是有的。在这记录一个好评比较多的一款。
该API接口需要先注册账户，注册后直接在个人中心找到API秘钥就可以进行对接开发。

请求示例：
使用HTTP请求查询贵金属行情价格
import timeimport requests # pip3 install requests
import json# Extra headers
test_headers = {'Content-Type' : 'application/json'
}'''

print(text1)code：查看官方给出的code列表，选择你要查询的code
kline_type： 指的是k线类型，1为1分钟K，2为5分钟K，3为15分钟K，4为30分钟K，5为小时K，6为2小时K，7为4小时K，8为日K，9为周K，10为月K
query_kline_num：查询多少根K线，最多1000根

接口同时支持websocket，下面展示使用websocket请求查询现货黄金/伦敦金（XAUUSD）的实时行情价格：
