Alchemy is launching AgentCard, a Visa-powered virtual card and identity solution that lets AI agents spend in the real world without a human in the loop. Built on Visa Intelligent Commerce, the card defaults to tokenized Visa payments but also routes through crypto rails and emerging agent-native protocols such as Coinbase's x402 and Stripe's Machine Payments Protocol when merchants accept them.
Setup is a single API call that hands the agent a Visa payment token plus a dedicated email, phone number, and crypto wallet. Spend controls, merchant restrictions, per-transaction limits, and budgets are baked in, so a developer can keep the agent on a leash even when it is transacting autonomously.
Why it matters
AgentCard is the third major agent-payments launch in roughly a month, after Mastercard's Agent Pay for Machines initiative and MetaMask's Agent Wallet. The clustering is the story: Visa, Mastercard, MetaMask, Stripe, and Coinbase are all building parallel rails for the same thesis — that autonomous software, not humans, will be the dominant initiator of low-value, high-frequency transactions. Alchemy's founder Nikil Viswanathan has long argued crypto rails were purpose-built for that world; AgentCard is the infrastructure bet that follows from it.
Market impact
The product sits on top of stablecoins and tokenized card networks, two of the most investable themes in payments right now. If agents become a non-trivial share of card-not-present volume, incumbent processors capture the fees while crypto-native protocols — x402, MPP, and stablecoin settlement — compete for the slices where Visa's reach is thin. Watch for developer adoption signals: API signups, first agent issuers, and which payment rail actually gets used when an agent is given a choice.
Frequently asked questions
-
What is Alchemy's AgentCard?
AgentCard is a Visa-powered virtual card and identity solution from blockchain infrastructure provider Alchemy that lets AI agents transact in the real world autonomously, with built-in spend controls and a single API setup.
-
How does AgentCard handle crypto payments?
AgentCard defaults to tokenized Visa payments but supports crypto and agent-native protocols such as Coinbase's x402 and Stripe's Machine Payments Protocol when merchants accept them, upgrading the payment path automatically as adoption grows.
-
What other agent payment products have launched recently?
Mastercard unveiled Agent Pay for Machines last week with dozens of fintech and crypto partners, and MetaMask launched Agent Wallet earlier this month, providing bots with self-custody access to the Ethereum ecosystem.
-
What spend controls does AgentCard offer developers?
Developers can set merchant restrictions, per-transaction limits, and budgets for each agent, so autonomous spending stays within defined guardrails even without a human approving each transaction.
-
Why does Alchemy's CEO think crypto is built for AI agents?
Founder Nikil Viswanathan has repeatedly argued that crypto rails were designed for autonomous, non-human actors rather than humans, framing AgentCard as the infrastructure layer that proves that thesis out in payments.
