QuantDB Python SDK

QuantDB 量化数据平台官方 Python SDK，提供同步与异步两种客户端，封装了全部 API 端点。

安装

pip install quantdb-sdk

开发依赖：

pip install -e ".[dev]"

快速开始

API Key 鉴权（推荐）

from quantdb_sdk import QuantDBClient

client = QuantDBClient(api_key="qdb_xxx...")

# 查询用量
usage = client.get_usage()
print(f"已用: {usage['used_gb']:.2f} GB, 剩余: {usage['remaining_gb']:.2f} GB")

# K 线查询（免费）
df = client.query_kline(
    "600519.SH",
    adj_type="forward",
    start_date="2026-01-01",
    end_date="2026-07-22",
)
print(df.head())

用户名密码鉴权

client = QuantDBClient(username="admin", password="admin123")

核心功能

数据查询：K 线、Tick 通过下载 Parquet 切片后客户端解析（消耗流量）；股票列表、交易日历、元数据走网关 JSON（不计流量）。
数据下载：Parquet 文件下载或直读 DataFrame，计入订阅流量。
本地分析：基于 DuckDB 对本地 Parquet 执行 SQL。
账户管理：查询用户信息、用量、API Key、订阅与订单。
异步客户端：基于 httpx，适用于 asyncio 量化框架。

流量说明

每月前 30 GB 下载流量免费，超出部分按 ¥1/GB 计费；账户余额不足时，下载会被限流，充值后即可恢复。
