FAQ from kospi-kosdaq-stock-server
What are the runtime requirements?
Python 3.10+, a Kakao account with 2FA disabled, and the Playwright Chromium browser installed.
How do I handle the “KakaoTalk login notification” on first run?
Run the server with headless=False to see the browser, approve the login request in KakaoTalk, and the session cookies will be saved for future use.
What if the session expires or I get a 401 error?
The server automatically renews the session (~4‑hour expiry). If auto‑renewal fails, delete ~/.krx_session.json and restart the server.
Does the server support Naver login?
Naver login is not yet implemented; only Kakao OAuth is supported.
Where does the stock data come from?
All data is fetched directly from the KRX Data Marketplace (data.krx.co.kr). No local storage of stock data is used.
