```Python
results = await some_library()

Entonces declara tus *path operation functions* con `async def` de la siguiente manera:

```Python hl_lines="2"
@app.get('/')
async def read_results():
    results = await some_library()
    return results
```

    * Si on n'utilisait pas FastAPI mais directement Starlette (ou un outil équivalent comme Sanic, Flask, Responder, etc) il faudrait implémenter la validation des données et la sérialisation par nous-même. Le résultat serait donc le même dans les deux cas mais du travail supplémentaire serait à réaliser avec Starlette, surtout en considérant que la validation des données et la sérialisation représentent la plus grande quantité de code à écrire dans une application....

 * Example of using a hardware key to perform client auth.

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*.
