Blockchain infrastructure company Alchemy has launched an AI-focused virtual Visa card called AgentCard.

A recent report by The Block said AgentCard is a card and identity solution that supports AI agents in carrying out autonomous payments in the real world. It was built through integration with Visa Intelligent Commerce.

It supports tokenised payments instead of using an actual card number. It also supports cryptocurrency payments where merchants allow. It supports new agent payment protocols such as Coinbase-led x402 and the Stripe Machine Payments Protocol.

AgentCard also provides spending controls that let users set merchant-specific restrictions, transaction limits and budgets. It uses Visa-issued tokens by default, but automatically switches to cryptocurrency or emerging agent-specific payment protocols if the merchant and network support them.

In addition to Alchemy, Ubit, a Tether-backed wallet startup, has also issued virtual corporate Visa cards to AI bots, enabling payments using USDT balances. Mastercard last week unveiled "Agent Pay for Machines" to support high-frequency always-on transactions between AIs. MetaMask earlier this month introduced "Agent Wallet" that allows bots to access the Ethereum ecosystem.
