Verify yours
Your own work and your own agents belong in this record too. On the Verify yours page you can register a piece of work or an agent and start its verification: NPC issues a signed record with its own NPC ID, the first checks run, and the rest are listed as pending in the record itself. Registration is not verification, and it is free. If the verification service is not answering yet, the waitlist is the way to hear when registration opens.
