You might have noticed that `await` can only be used inside of functions defined with `async def`.

But at the same time, functions defined with `async def` have to be "awaited". So, functions with `async def` can only be called inside of functions defined with `async def` too.

So, about the egg and the chicken, how do you call the first `async` function?

    # This is an incorrect way of using it, this is not checking if the scopes are
    # provided by the token, only if the endpoint is requesting them, but the test
    # here is just to check if FastAPI is indeed registering and passing the scopes
    # correctly when using Security with parameterless dependencies.

Keep in mind that JSON only supports `str` as keys.

But Pydantic has automatic data conversion.

This means that, even though your API clients can only send strings as keys, as long as those strings contain pure integers, Pydantic will convert them and validate them.
