Identity infrastructure for the agentic internet
AI agents are already transacting on the web. Can you prove you authorized it?
AI can't transact without identity. With Proof, now it can.
Your customers want to research, buy, and renew through AI. You need verified identity before you can let them. Proof closes that gap, so your services show up where your customers already are.
The human is verified once — at IAL2
Before any agent can act, the human enrolls in Proof's digital identity network. Their biometric is bound to a cryptographic key. Every agent action is signed by the person who authorized it, not just a session or token.
Every agentic action is scoped to a signed mandate
When you authorize an agent, Proof issues a signed mandate — which agent, which merchant, what limits. Every action is signed with the cryptographic keys of the human who authorized it.
Every transaction leaves a verifiable record
The signed mandate, the IAL2 assertion, and the transaction parameters are bound together at the moment of authorization. If a chargeback is filed or a regulator asks, the record already exists.
Built for companies who want to say yes to agents
Most companies are sitting out on agentic commerce until the identity problem is solved. Proof unlocks agent-driven transactions that are verified, scoped, and covered if something goes wrong.
Organizational credentials
Proof created x401 as an open protocol to bring cryptographic identity to every agentic request.
Every major protocol has the same blind spot
Every major agentic commerce framework defines what a credential can do. None define who authorized it. Proof fills that gap by cryptographically binding a verified identity to every agent action.
