View APIWhat is Zero Proof?
Zero Proof provides a security layer for AI agents that shop, negotiate, and transact on behalf of users. As AI agents start making purchases for millions of people, we ensure every transaction is verified and secure.
Built to support OpenAI's Agentic Commerce Protocol, Zero Proof uses zero-knowledge proofs to verify agent identity and authorization without exposing sensitive credentials.
How it works
Request Challenge
Your agent requests a verification challenge from our API, providing its ID and intended action.
Generate Proof
The agent generates a zero-knowledge proof using the challenge nonce, proving its identity without revealing secrets.
Verify & Authorize
Our API verifies the proof and returns a verification result with confidence score. The transaction can proceed securely.
