FastAPI Documentation

FastAPI automatically generates documentation for your instance. It can be accessed via:
```
127.0.0.1:8000/doc
```

Or:

```
127.0.0.1:8000/redoc
```

You can customize the JSON response from FastAPI using the @app.get decorator. For example:

```python
from typing import Optional
from fastapi import FastAPI

app = FastAPI()

@app.get("/items/{item_id}")
def read_item(item_id: int):
    if item_id == 1:
        return {item_id: "One"}
    else:
        return {item_id: None}
```

Acessing 127.0.0.1:8000/items/1 returns:
```
{"1":"One"}
```
And 127.0.0.1:8000/items/2 returns:
```
{"2":"null}
```
