Verified by NPC plugin

The plugin answers "is this real?" inside your conversation. You can ask it to check a product's smart tag, a certificate or credential, a claim, or an AI agent's verification status, or ask what a verification result means.

• An "unknown" answer means NPC Labs has no record of what you asked about. It is never a guess, and it is never a claim that something is false.
• Trying the demo: ask about the demo fixtures: product tag demo-tag-001, credential demo-cred-001, agent demo-agent-001.
• The plugin cannot issue verifications. It verifies only. If you ask it to record an attestation or to explain its checking methodology, it will decline.
