Official Python SDK for QOS Market Data API.

Project description

QOS行情API Python SDK

PyPI version Python versions

官方Python SDK for QOS行情API,支持港股、美股、A股和加密货币的实时行情数据,K线数据,历史K线数据,直接提供了港股API,美股API,A股API,加密货币API。

功能特性

  • 完整实现所有7个HTTP接口和11个WebSocket命令
  • 强类型检查(基于Pydantic)
  • 同步HTTP客户端和异步WebSocket客户端
  • 自动重连和心跳维护
  • 完善的错误处理机制

安装

pip install qos-api

注册API KEY

注册api key

快速开始

初始化客户端

注册api key

from qos_api import QOSClient

client = QOSClient(api_key="您的API_KEY")

HTTP接口使用示例

获取品种基础信息

# 获取股票基础信息
info = client.get_instrument_info(["US:AAPL", "HK:00700", "SH:600519"])
print(info)

获取实时行情快照

# 获取实时行情
snapshot = client.get_snapshot(["US:TSLA", "HK:09988"])
print(snapshot)

获取K线数据

from qos_api.constants import KLineType

# 获取日K线
kline = client.get_kline(
    codes=["SH:600519"],
    ktype=KLineType.DAY.value,
    count=10
)
print(kline)

WebSocket接口使用示例

实时行情订阅

注册api key

import asyncio
from qos_api import QOSClient

async def handle_snapshot(snapshot):
    print(f"行情更新: {snapshot}")

async def pull_snapshot_periodically(client):
    """每10秒主动请求一次快照"""
    try:
        while True:
            data = await client.request_snapshot(["US:AAPL"])
            print(f"手动拉取快照数据: {data}")
            await asyncio.sleep(10)
    except asyncio.CancelledError:
        print("快照任务已取消")
        raise

async def main():
    client = QOSClient(api_key="您的API_KEY")
    client.register_callback("S", handle_snapshot)
    await client.connect_ws()
    await client.subscribe_snapshot(["US:AAPL", "HK:700"])

    # 启动后台任务
    snapshot_task = asyncio.create_task(pull_snapshot_periodically(client))

    try:
        while True:
            await asyncio.sleep(1)
    except KeyboardInterrupt:
        print("收到退出信号,正在清理...")
        snapshot_task.cancel()
        await asyncio.gather(snapshot_task, return_exceptions=True)
        await client.close()
        print("已优雅退出")

if __name__ == "__main__":
    try:
        asyncio.run(main())
    except KeyboardInterrupt:
        # 再次捕获,防止 asyncio.run 抛出错误
        print("主程序强制退出")

请求实时数据

注册api key

import asyncio
from qos_api import QOSClient
from qos_api.constants import KLineType

async def request_realtime_data():
    client = QOSClient(api_key="您的API_KEY")
    await client.connect_ws()
    
    # 请求实时行情
    snapshot = await client.request_snapshot(["US:AAPL"])
    print(snapshot)
    
    # 请求K线
    kline = await client.request_kline(
        codes=["HK:700"],
        ktype=KLineType.DAY.value,
        count=10
    )
    print(kline)

asyncio.run(request_realtime_data())

完整API参考

HTTP接口

方法 描述 对应API
get_instrument_info(codes) 获取品种基础信息 GET /instrument-info
get_snapshot(codes) 获取实时行情快照 GET /snapshot
get_depth(codes) 获取盘口深度 GET /depth
get_trades(codes, count) 获取逐笔成交 GET /trade
get_kline(codes, ktype, count, adjust) 获取K线数据 GET /kline
get_history_kline(codes, ktype, end_time, count, adjust) 获取历史K线 GET /history

WebSocket接口

订阅管理

方法 描述 对应命令
subscribe_snapshot(codes) 订阅实时快照 S
unsubscribe_snapshot(codes) 取消订阅快照 SC
subscribe_trades(codes) 订阅逐笔成交 T
unsubscribe_trades(codes) 取消订阅逐笔 TC
subscribe_depth(codes) 订阅盘口数据 D
unsubscribe_depth(codes) 取消订阅盘口 DC
subscribe_kline(codes, ktype) 订阅K线数据 K
unsubscribe_kline(codes, ktype) 取消订阅K线 KC

数据请求

方法 描述 对应命令
request_snapshot(codes) 请求实时快照 RS
request_trades(codes, count) 请求逐笔成交 RT
request_depth(codes) 请求盘口数据 RD
request_kline(codes, ktype, count) 请求K线数据 RK
request_history_kline(codes, ktype, end_time, count) 请求历史K线 RH
request_instrument_info(codes) 请求品种信息 RI

连接管理

方法 描述
connect_ws() 建立WebSocket连接
disconnect_ws() 断开WebSocket连接
heartbeat() 发送心跳包
register_callback(data_type, callback) 注册数据回调

数据模型

所有返回数据都使用Pydantic模型,主要模型包括:

  • InstrumentInfo: 品种基础信息
  • QuoteSnapshot: 行情快照
  • MarketDepth: 盘口深度
  • TradeTick: 逐笔成交
  • KLine: K线数据

错误处理

所有异常都继承自 QOSAPIError

from qos_api import QOSAPIError

try:
    data = client.get_snapshot(["US:AAPL"])
except QOSAPIError as e:
    print(f"API错误: {e.code} - {e.message}")

限制说明

  1. 默认每个连接最多订阅10个品种
  2. HTTP请求频率限制为每分钟10次
  3. WebSocket消息间隔需大于1秒
