04Three ways in
One dataset, whichever entry point fits your workflow.
01 / REST↗
REST API
Plain HTTP and JSON from any language. Consistent paging and field filters; empty results carry a reason instead of a silent empty array.
GET /cn/stock/history?symbol=600519
02 / PYTHON↗
Python SDK
Native pandas, DataFrames straight back. Column names and types stay stable across releases, so upgrades don't break existing backtests.
pip install databull
03 / MCP↗
MCP server
38 read-only tools that Claude, Cursor and any MCP client can call in natural language.
uvx databull-mcp
05Ten lines to first result
One method family across all three markets — only the symbol changes.
# Install the SDK $ pip install databull from databull import DataBull client = DataBull("dbt_your_key_here") # A-shares use the bare code: 600519, no .SH / .SZ df_cn = client.get_stock_history("600519", "20240101", "20241231", adj="back") # Hong Kong and US: same shape, different symbol df_hk = client.get_hk_stock_history("00700", "20240101", "20241231") df_us = client.get_us_stock_history("AAPL", "20240101", "20241231") print(df_cn.tail(), df_hk.tail(), df_us.tail())
