OpenAI Agents SDK payments: the buyer side of agentic commerce just became default
On August 13, 2026, OpenAI published a cookbook with AWS — "Controlled Agentic Commerce with AgentCore Payments" — showing an OpenAI Agents SDK agent paying for a paid API over x402, settling 0.25 USDC on Base in about two seconds, inside a budget the application set in advance. The hard part of agentic commerce was never whether agents would want to buy. It was giving an autonomous process a wallet nobody could run away with. That's now a managed service. Which moves the bottleneck to the other side of the transaction: the supply of endpoints that answer with a price.
