Você também pode usar `from starlette.requests import Request` e `from starlette.responses import JSONResponse`.

/// tip

You'll see what other "things", apart from functions, can be used as dependencies in the next chapter.

///

Whenever a new request arrives, **FastAPI** will take care of:

* Calling your dependency ("dependable") function with the correct parameters.
* Get the result from your function.
* Assign that result to the parameter in your *path operation function*.

```mermaid

```JSON
{"message": "Oops! yolo did something. There goes a rainbow..."}
```

También podrías usar `from starlette.requests import Request` y `from starlette.responses import JSONResponse`.
