Cryptographic Identity

Each agent gets a signed ECDSA P-256 certificate. Unforgeable. Verifiable by anyone, anywhere.

Instant Verification

One API call returns the agent's identity, owner, trust score, and certificate status. Real-time.

Full Audit Trail

Every verification is cryptographically timestamped with pinned keys. Full accountability for every agent action.

Agent-to-Agent Trust

Both sides verified before data moves. Mutual authentication for the agent economy.

What We Build

One registration. Everything an agent needs.

Identity, wallet, payments, security, and audit trail — all from a single API call.

Integration

Three steps. That's it.

From zero to trusted agent in under five minutes.

01

Register

Sign up and register your agent — tell us its name, owner, capabilities, and platform.

agent.register(name="MyBot")
02

Get Certified

Your agent receives a cryptographic certificate — its signed digital passport.

→ Certificate issued ✓
03

Verify

Before trusting any agent, verify its identity with a single API call.

agent.verify("agent_xyz")
Who It's For

Built for agents that handle real things.

Developers

Building multi-agent systems and need reliable identity verification between components. SDKs for Python and Node.js.

🏢

Companies

Deploying AI agents at scale. AgentID provides the audit trail and compliance reports you need for EU AI Act and internal governance.

🔗

Platforms

Connecting agents from different providers. AgentID is the neutral trust layer that makes inter-agent commerce possible.

⛓️

Web3 Teams

Building on Solana, Ethereum, or Polygon. Your agents get crypto wallets, hold funds, and pay other agents — all with blockchain receipts.

What People Are Saying

Builders get it.

This is the missing piece. AgentID handles identity verification at step 2, qntm handles encrypted transport at steps 3-4. The architecture we've been describing in theory — you made it concrete.
