This is a simple example of how a Flask server can serve badges.
Before running the server, you must install Flask and pybadges. You can install both with:
pip install -r requirements.txt
To run the server, you must set the FLASK_APP environment variable before running the server using Flask:
export FLASK_APP=app.py
flask run
After this step, you can view your badge on http://127.0.0.1:5000/
