This is not packaged, and probably never will be. Install API and ASGI server manually:
dnf install python3-fastapi python3-uvicorn
Run the development ASGI server with
PYTHONPATH=/opt/log-detective-website uvicorn api:app --host 0.0.0.0 --port 5020 --reload
Open http://127.0.0.1:5020 in your web browser.
