This app helps you to get historical stock prices of the last year given a CSV input file including the German WKN (Wertpapierkennnummer) of the security.
I used the OpenFIGI API (usable with and without an API Key) to translate the WKN into the international ticker base and the yfinance package from Ran Aroussi to fetch the stock prices.
The app works with a Streamlit Framework and is deployed on Heroku.
