Circle and Proof plan to demonstrate an AI agent making payments in USD Coin (USDC) while proving buyer authorization at the Money20/20 conference in Las Vegas from October 19-21. Their system uses Proof’s x401 protocol for identity verification and Coinbase-developed x402 for payment authorization, allowing merchants to confirm who approved the purchase. This technology aims to enable automated checkouts with clear authorization records, enhancing trust and security in AI-driven payments. The demo will showcase how AI agents can securely pay merchants while providing proof of buyer consent, with potential future extensions involving merchant payments to identity providers.
