Alchemy, the blockchain infrastructure company, today unveiled AgentCard — a payment product that lets AI agents make online purchases using Visa’s network. The card gives autonomous software a dedicated payment credential, but with guardrails: users set spending limits, track every transaction in real time, and decide which merchants the agent can use. It’s an attempt to bridge the gap between programmable money and the everyday card rails the internet still runs on.
Borrowing from crypto, working on card rails
AgentCard draws on ideas from programmable finance — the team name-checks crypto standards like x402 — but it plugs into Visa’s existing payment infrastructure. That means an AI agent can check out at any online store that accepts Visa, without the merchant doing anything special. Alchemy handles the identity layer, the wallet, and the spending rules; Visa moves the money. The goal is to give developers a safe way to let agents buy cloud compute, APIs, or even physical goods without handing over a human’s credit card number.
Spending limits and user control
The whole pitch rests on control. AgentCard doesn't just give an agent a blank check. Users set a maximum spend per transaction, per day, or per month. They can restrict the card to specific merchant categories or even individual websites. Every purchase shows up in a dashboard with real-time tracking. If an agent tries to spend outside its bounds, the transaction fails. That level of constraint is meant to make the idea palatable to people who still flinch at letting an AI book a flight.
The bigger race for agent payments
Alchemy isn’t alone in chasing this. Visa and Mastercard both have their own intelligent commerce initiatives aimed at machine-initiated payments. On the crypto side, developers are pushing machine-to-machine payment standards that bypass card networks entirely. AgentCard sits in the middle — it uses crypto-style programmability but lives on the rails merchants already trust. Alchemy sees itself as the infrastructure layer for the agent economy, offering identity, wallets, and spending rules as building blocks for developers.
The product’s success will depend on two things: whether merchants are comfortable taking orders from automated buyers, and whether users can learn to trust an agent with money. Neither is guaranteed. But for now, AgentCard gives the second group a reason to try.
