## Overview

This is a minimal FastAPI HTTP service with a greeting endpoint and a health-check endpoint. When run directly, main.py starts Uvicorn to serve the app. The source shows route registration and startup; the README is empty, so no further capabilities are documented.

Main entry points: [`main.py`](https://github.com/csallahbakash/fastapi-basics/blob/master/main.py) (FastAPI app)
