+The project defines the following packages in `pyproject.toml`:
 
 1. **`fastapi`**: The core web framework for building APIs with Python 3.8+ based on standard Python type hints. It provides high performance (on par with NodeJS and Go), rapid coding, and automatic interactive Swagger/ReDoc documentation.
 2. **`uvicorn[standard]`**: An ASGI (Asynchronous Server Gateway Interface) web server implementation for Python. FastAPI is built on ASGI standard, and `uvicorn` acts as the server to run the FastAPI application. The `[standard]` extra installs high-performance loop dependencies like `uvloop` and `httptools`.
