The primary key has full access. A named key can be scoped: none, read or write per resource, limited to some workflows or to approved sessions, to a list of IP addresses, and to an expiry date. 401 means the key is missing, wrong, revoked or expired; 403 means the key has no access to this resource or action, or the request came from an address outside its IP list; 404 on a session route means the session is outside the key's workflows or statuses. A key without media access receives image, video and PDF URLs as null, and a key without sessions write receives session links and tokens as null.
