yafin 0.1.0

Unofficial Yahoo Finance API asynchronous client

Yafin

Unofficial Yahoo!Ⓡ finance Python API client.

• Not affiliated with Yahoo, Inc.
• Open source library that uses publicly available APIs.
• Intended for research, educational purposes and personal use only.
• Synchronous and asynchronous.
• Not returning pandas dataframes (because why?).
• Uses caching and utilizes singleton pattern in symbol class to save resources.
• Minimal and build on curl-cffi
• Approx. 2x faster, than other Yahoo finance clients. Run the tests yourself - make test-perf (All tests running synchronously, returning pandas DataFrame and http responses are mocked.)
