You already created an API that:

* Both _paths_ take `GET` operations (also known as HTTP _methods_).
* The _path_ `/items/{item_id}` has a _path parameter_ `item_id` that should be an `int`.

 * <p>Bloom filters are serializable. They also support a more compact serial representation via the

 * of the code may not be readable by older versions of the code (e.g., a serialized Bloom filter
