The path ID must be a UUID. A missing item and an item belonging to another merchant both return 404 ITEM_NOT_FOUND.

An archived item remains readable, but cannot be used for a new invoice from item. archived_at contains the archival timestamp when archived.

Sign {} for the bodyless GET. The item ID is in the path and is not included in the current signature payload.
