Mastercard opened early access to Agent Pay for Machines on Oct. 20, 2026, giving developers buyer- and seller-side APIs, a developer toolkit and a sandbox after end-to-end testing with multiple partners. The system is designed to let AI agents discover paid services, agree to terms and pay for them within spending limits set by humans. The project remains in the pilot stage and has not yet been made commercially available.
Mastercard first announced Agent Pay for Machines in June with support for spending controls and payments using cards, bank accounts and stablecoins. Developers participating in early access are being asked to test the APIs and provide feedback on additional capabilities. End-to-end pilots have involved partners including Cloudflare, Ant International, BVNK and Coinbase.
AI agent completes campaign purchases at Cloudflare Connect
Mastercard’s Jorn Lambert demonstrated a live transaction at Cloudflare Connect using an AI agent working for marketing agency Hype. Hype assigned the agent to prepare a campaign for a protein-bar launch under an approved budget. The agent purchased social-media research from AIsa and obtained eight campaign images through Cloudflare AI Gateway, completing nine payments to two independent providers without requiring separate accounts or invoices.
Agent Pay for Machines builds on the Coinbase-incubated x402 protocol, which takes its name from the HTTP 402 “Payment Required” status code. The protocol allows websites, APIs and AI agents to request and receive payments through blockchain-based and traditional payment rails. When a paid service requests payment, the agent generates a digitally signed payment voucher within its authorized spending limit. The provider verifies the voucher before delivering the requested service.
Mastercard said the payment vouchers can be batched and redeemed later instead of requiring each transaction to settle separately. The interactions can therefore take place off-chain before providers redeem the vouchers, allowing an AI agent to purchase services as it carries out an assigned task.
Coinbase, Base and BVNK provide payment infrastructure
Coinbase Developer Platform supplied the wallet infrastructure used to fund the Hype agent, while Base served as the onchain settlement network. BVNK, the stablecoin infrastructure company Mastercard acquired in August, supported the agent wallet and used Mastercard’s Global Money Platform to process payment and settlement in fiat or stablecoins.
The setup also allows sellers to receive funds through their preferred currency, token or payment rail. The payment architecture connects an agent’s approved spending authority with the service provider’s payment request rather than requiring the agent to establish a conventional billing relationship with every provider it selects.
“The web gave software a way to communicate. APIs gave software a way to use services. Now AI agents need a way to pay for them,” Mastercard said. “That’s what we’re building.”
The early-access program follows Mastercard’s broader work around agent and stablecoin payments, including its Stablecoin Security risk tool and the BVNK-powered Global Money Platform.
