Check whether a certificate or credential is real. Check a claim against NPC Labs' attestation records. Check an AI agent's verification status. Or learn what a verification result means. Results come back signed by NPC Labs, so the answer can be checked independently of the connection it arrived over. When NPC Labs has no record of the subject, the answer is 'unknown'. Unknown is never a claim that something is false. The plugin only verifies; it cannot issue attestations.",
