You can think of `APIRouter` as a "mini `FastAPI`" class.

All the same options are supported.

All the same `parameters`, `responses`, `dependencies`, `tags`, etc.

/// tip

In this example, the variable is called `router`, but you can name it however you want.

///

We are going to include this `APIRouter` in the main `FastAPI` app, but first, let's check the dependencies and another `APIRouter`.

	// SPECIAL CASE: For service accounts, any valid JSON is allowed as a
	// policy, regardless of whether the number of statements is 0, this
	// includes `null`, `{}` and `{"Statement": null}`. In fact, MinIO Console
	// sends `null` when no policy is set and the intended behavior is that the
	// service account should inherit parent policy. So when policy is empty in
	// all fields we return hasSessionPolicy=false.
