Setup and Running

1. Install dependencies:

pip install -r requirements.txt

2. Run migrations:

alembic upgrade head

python main.py

The API will be available at http://localhost:8000. API documentation is available at:

• Swagger UI: http://localhost:8000/docs
• ReDoc: http://localhost:8000/redoc

Database

The application uses SQLite as its database, stored at /app/storage/db/db.sqlite. SQLAlchemy is used as the ORM layer to interact with the database.
