## What it is
AData is a free, open-source Python library providing market data for China's A-share stock market, including stock codes, K-line quotes, ETFs, bonds, and concept data. It fuses multiple public data sources with dynamic proxy support to keep data access highly available for individual quantitative traders.

## Use cases
- fetch historical kline data for chinese a-share stocks
- get all stock codes on the shanghai and shenzhen exchanges
- download free stock market data for quantitative trading in python
- query etf and bond market data for china
- build a personal quant trading data pipeline without paid data feeds
- switch between multiple data sources when one public api fails

## When to choose
- you need free access to China A-share market data in Python
- you want a lightweight pip-installable sdk for stock quotes and klines
- you need multi-source fallback and proxy support for data reliability
- you are an individual quant trader avoiding paid data subscriptions

## When to avoid
- you need global markets outside China's A-shares
- you require guaranteed SLA-grade data quality or tick-level data
- you need a full backtesting or trading execution framework rather than data access
