Alchemy Unlocks AI Agent Purchases Anywhere Mastercard is Accepted Online via AgentCard

The unified payments and identity product will integrate Mastercard Agent Pay and is designed to support Verifiable Intent, extending trusted agentic payments to developers, consumers and businesses alike.

SAN FRANCISCO, Sept. 17, 2026 /PRNewswire/ -- Alchemy, the leading AI developer and infrastructure platform for the onchain economy, today announced that AgentCard will support Mastercard payment credentials through an integration with Mastercard Agent Pay, giving developers a simple way to build AI agents that can safely complete purchases for users online. The integration brings together Alchemy's agent infrastructure and Mastercard's trusted payments network to help agents move beyond recommendations and take action, with user authorization, issuer controls, payment protections and support for verifiable proof of intent built in.

With AgentCard, developers can enable AI agents to make online purchases on a user's behalf, from ordering food and booking travel to managing digital subscriptions. Through a single CLI, developers can set up AgentCard in under a minute and equip an agent with the identity and payment tools it needs to exist, act and transact online: a dedicated email address, phone number, stablecoin wallet and one-time-use Mastercard payment credentials. The stablecoin wallet gives agents access to emerging agentic payment protocols, while one-time-use Mastercard payment credentials enable purchases at the many online merchants that still rely on traditional credit card rails. Users and issuers can set clear controls for how an agent spends, including purchase limits, merchant categories, and where transactions are allowed, so agents can only act within approved boundaries.

AgentCard integrates with Mastercard Agent Pay, the payments network's framework for trusted and secure agentic commerce. Through these integrations, agents can transact using one-time-use, tokenized Mastercard payment credentials linked to a user's existing Mastercard, preserving existing rewards, credit lines, and card benefits without creating new accounts or credentials. AgentCard is also designed to support Verifiable Intent, Mastercard's framework for proving that an agent acted within the user's authorized instructions, helping consumers, merchants and issuers understand what was approved, under what conditions and by whom.

"AI agents are quickly moving from simple assistants to software that can take action for people," said Nikil Viswanathan, co-founder and CEO of Alchemy. "To make that possible in everyday commerce, agents need a trusted way to pay, prove authorization, and operate within clear user-defined limits. By working with Mastercard, AgentCard can help developers bring agentic commerce into the mainstream with the security and reliability people expect from modern payments."

"The future of commerce isn't just about agents that can act—it's about agents that can be trusted to act on your behalf," said Sherri Haymond, EVP of Digital Commercialization. "Mastercard Agent Pay brings the trust, safeguards and consumer control needed to help agentic commerce move from experimentation to everyday use."

Developers can program custom agents to use AgentCard through the CLI, bringing identity, wallet and payment capabilities into the experiences they build. Consumers can simply ask their agent to sign up at AgentCard.ai for a seamless, out-of-the-box experience. Businesses can choose the approach that fits their needs: deploy a ready-made experience quickly, or deeply integrate AgentCard's capabilities into their own products and workflows.

As AI agents take on a greater role in discovering products, making decisions, and completing transactions, trusted frameworks for identity, authorization and payments will become increasingly important. The collaboration between Alchemy and Mastercard reflects a broader industry shift toward secure, consumer-controlled agentic commerce.

AgentCard is available today at agentcard.ai. Provision your first agent in under a minute.
