Blockchain infrastructure company Alchemy has launched an AI-focused virtual Visa card called AgentCard. The card and identity solution is designed to let AI agents make autonomous payments in the real world and was built through integration with Visa Intelligent Commerce. It supports tokenised payments instead of using an actual card number and, where merchants allow, cryptocurrency payments. The service also supports new agent payment protocols such as Coinbase-led x402 and the Stripe Machine Payments Protocol.
