Developers used to build software that executed commands. Now, we’re building agents that make decisions.
That shift—from code that acts to code that chooses—is redefining automation. And the next evolution is already here: agents that transact.
The buzz around x402, Coinbase’s new payment protocol for APIs, is well deserved. It enables AI agents to purchase access to web data, APIs, and digital services using crypto — no accounts, no subscriptions, no human-in-the-loop.
But the bigger shift isn’t technical. It’s conceptual. When you give an agent a wallet, you give it economic identity. That opens up a radically new design space.
This isn’t new plumbing for APIs. It actually changes how we think about permissions, trust, and accountability.
