**FastAPI** calls the `CommonQueryParams` class. This creates an "instance" of that class and the instance will be passed as the parameter `commons` to your function.

## Type annotation vs `Depends` { #type-annotation-vs-depends }

Notice how we write `CommonQueryParams` twice in the above code:

```Python
