## Overview

This is a small FastAPI task API. A client sends HTTP requests to the application, which mounts task routes for API-key-protected listing, filtering, lookup, creation, update, and deletion. The routes use Pydantic models for request and response shapes and operate on a process-local in-memory task list. The graph reflects the sampled source; no README was provided.

Main entry points: [`app/routers/tasks.py`](https://github.com/kanvad/fastapi_basic/blob/main/app/routers/tasks.py) (Task routes), [`app/main.py`](https://github.com/kanvad/fastapi_basic/blob/main/app/main.py) (FastAPI app), [`app/schemas.py`](https://github.com/kanvad/fastapi_basic/blob/main/app/schemas.py) (Task schemas), [`app/data.py`](https://github.com/kanvad/fastapi_basic/blob/main/app/data.py) (In-memory tasks)

## Components

### API runtime

- [FastAPI app](https://github.com/kanvad/fastapi_basic/blob/main/app/main.py): `app/main.py`
- [Task routes](https://github.com/kanvad/fastapi_basic/blob/main/app/routers/tasks.py): `app/routers/tasks.py`

### Data contracts

- [Task schemas](https://github.com/kanvad/fastapi_basic/blob/main/app/schemas.py): `app/schemas.py`

### Task state

- [In-memory tasks](https://github.com/kanvad/fastapi_basic/blob/main/app/data.py): `app/data.py`

### Other components

- **API client**

## Connections

- API client → FastAPI app: sends HTTP
- FastAPI app → Task routes: mounts routes
- Task routes → Task schemas: declares models
- Task routes → In-memory tasks: reads and mutates
