How x402 Works

Our first product: privacy-preserving payment protocol

Anonymous Credential Issuance

Agent obtains blinded credentials from payment provider without revealing identity or destination.

Privacy-Preserving Payment

x402 challenge is met with unlinkable proof. Merchant verifies payment without learning agent history.

Selective Compliance

Regulatory requirements met through zero-knowledge proofs, revealing only what's legally required.

x402 Privacy Protocol

Cryptographic separation of payment and identity

Privacy for Every Agent Interaction

Protecting agent privacy across payments, data, and beyond

Private Payments (x402)

Agents pay for services without revealing browsing patterns or creating linkable payment trails.

Confidential Data Access

Access sensitive data and APIs while protecting query patterns and usage behavior.

Anonymous Compute
