Machine-to-Machine Transactions
Automated digital asset exchanges between systems without human intervention.
What is Machine-to-Machine Transactions?
Machine-to-machine (M2M) transactions, facilitated by the x402 protocol, allow automated systems, such as AI agents or bots, to exchange digital assets for resources over the web. Unlike human-driven payments (e.g., entering credit card details), M2M transactions use standardized HTTP 402 responses to negotiate and settle payments programmatically. Examples include an AI agent paying for real-time data feeds or a crawler paying per page accessed, enabling efficient, scalable digital asset exchanges.
