# Mastercard Opens Early Access to Agent Pay for Machines

*Mastercard released first-version buyer and seller APIs, a sandbox and documentation for AI agents that pay for digital services over x402.*

Mastercard opened early access to Agent Pay for Machines on October 20, 2026, giving developers first-version buyer-side and seller-side APIs, a toolkit, a sandbox for testing buyer and seller flows, and documentation. The company said the release is not generally available and that customer and partner feedback will shape the roadmap.

The system runs on x402, an open protocol that uses the HTTP 402 Payment Required response to ask for payment. Mastercard first announced the service in June 2026 for high-frequency, low-value payments made by AI agents and software, extending its Agent Pay program from 2025.

Pilots ran end to end with Cloudflare, Ant International, AIsa, Base, BVNK and Coinbase. In a live demonstration at Cloudflare Connect, Mastercard's Jorn Lambert ran a test in which marketing agency Hype gave an agent one task: plan a sample campaign for a protein bar launch within a set budget. The agent, running on Amazon Bedrock AgentCore, bought social media research from AIsa and campaign images through Cloudflare's AI Gateway, making nine payments to two merchants from one budget. Cloudflare's Monetization Gateway issued the 402 payment requests, Coinbase Developer Platform supplied the wallet infrastructure that funded the agent, Base handled onchain settlement, and BVNK, which Mastercard acquired in August, handled payment and settlement in fiat or stablecoins through Mastercard Global Money Platform.

Each time a seller asks for payment, the agent signs a voucher, a promise to pay within its approved limit. The seller verifies the voucher and delivers. Vouchers are processed offchain, and providers can batch and redeem them later, so the agent never holds unlimited spending authority. The demonstration needed no separate accounts, API keys or invoices. "Payments aren't the hard part. Authority is," [Mastercard said](https://www.mastercard.com/us/en/news-and-trends/press/2026/october/Mastercard-Agent-Pay-for-Machines-in-action.html). The company says the voucher model could extend to AI models, data, computing power and other digital services.
