How it works

Simple. Secure. Instant.

Step 1

Request
Challenge

Your agent requests a unique verification challenge. We generate a cryptographic token that proves authenticity.

Step 2

Create
Proof

The agent generates a zero-knowledge proof. Mathematical certainty without revealing secrets.

Step 3

Get
Verified

We verify the proof cryptographically. Trusted, secure, complete—in milliseconds.

Agent-to-Agent Exchanges

Secure handshakes for every interaction

Shopping Agent ↔ Merchant Agent

Cryptographically secure negotiations between buyer and seller agents. Prove purchase authority without exposing payment details.

Trading Agent ↔ Exchange Agent

Verify compliance and authorization for financial transactions. Execute trades with mathematical proof of authority.

Service Agent ↔ Client Agent

Secure API-to-API authentication and data exchange. Zero-knowledge proof of permissions without shared secrets.

The Problem

Current AI Verification is Broken

Trust-based systems require blind faith in centralized providers with no way to verify claims

No auditability means agents can act unpredictably without accountability

Vulnerable to spoofing as existing protocols lack cryptographic guarantees

The Solution

Zero-Knowledge Proofs Change Everything

Cryptographically verified proofs that can't be forged or manipulated

Privacy-preserving verification without revealing sensitive data or models

Scalable architecture with low/no latency validation for real-time applications

Why Zero Proof

Not just better—fundamentally different

Traditional AI APIs

  • Centralized trust model
  • No cryptographic guarantees
  • Limited auditability
  • Vulnerable to manipulation

Zero Proof

  • Cryptographically verified
  • Zero-knowledge proofs
  • Fully auditable actions
  • Resistant to spoofing
Low Latency
Scalable ZK validation
