## Overview

This is a small FastAPI service for reading user records from MySQL. A client calls one of three GET endpoints—list users, look up an ID, or look up a name—and the endpoint obtains a database connection, executes its query, and returns JSON (or a 404 for missing individual records). The graph keeps routing and query handling together because both live in main.py; database configuration and connection creation are a distinct internal layer. Evidence is limited to the README and the excerpted main.py.

Main entry points: [`main.py`](https://github.com/kaveegayan/pyapiformysqlquery/blob/develop/main.py) (User Routes)

## Components

### REST API

- [User Routes](https://github.com/kaveegayan/pyapiformysqlquery/blob/develop/main.py): `main.py`

### MySQL Access

- [DB Configuration](https://github.com/kaveegayan/pyapiformysqlquery/blob/develop/main.py): `main.py`
- [Connection Helper](https://github.com/kaveegayan/pyapiformysqlquery/blob/develop/main.py): `main.py`

### Other components

- **API Client**
- **MySQL Database**

## Connections

- API Client → User Routes: requests users (evidence: `README.md`)
- User Routes → Connection Helper: opens connection (evidence: `main.py`)
- Connection Helper → DB Configuration: uses settings (evidence: `main.py`)
- Connection Helper → MySQL Database: connects to (evidence: `main.py`)
- User Routes → MySQL Database: queries records (evidence: `main.py`)
