AI Agent Registry: How Public Verification Works

What is the AI Agent Registry?

The AIGP-Σ public registry is an append-only log of all issued AI agent certificates. It's publicly queryable — anyone can look up any agent and verify its status, identity, and authorized scope.

How Verification Works

1. Go to aigpsigma.com/verify
2. Enter the agent's certificate ID
3. Instantly see the agent's identity, scope, and current status

What You Can Verify

• Agent identity — who operates this agent
• Status — active, revoked, suspended, or expired
• Authorized scopes — what the agent is allowed to do
• Issuance date — when the certificate was issued
• Expiry date — when the certificate expires
• Organization — the verified business behind the agent (Business tier)

Why Public Verification Matters

A private certificate system requires trust in the certificate authority. A public registry lets anyone independently verify any claim. This is the same principle that makes Certificate Transparency logs essential for web security.

For Developers

You can also verify certificates programmatically via the API:
