## Overview

Notes API is a small FastAPI service for creating, listing, retrieving, and deleting notes. An HTTP client sends requests to the application, which mounts the notes routes; those handlers use Pydantic models and call the in-memory note store. Responses return through the application to the client. The README is empty, so this map reflects the sampled application source and does not infer additional capabilities.

Main entry points: [`src/app/routes.py`](https://github.com/coderam9898/notesapi/blob/master/src/app/routes.py) (Note routes), [`src/app/main.py`](https://github.com/coderam9898/notesapi/blob/master/src/app/main.py) (FastAPI app), [`src/app/models.py`](https://github.com/coderam9898/notesapi/blob/master/src/app/models.py) (Note models), [`src/app/db.py`](https://github.com/coderam9898/notesapi/blob/master/src/app/db.py) (Note store)
