OpenAI introduced Instant Checkout inside ChatGPT for Plus, Pro, and Free users.

Instant Checkout is a way for shoppers to find and buy your products directly inside ChatGPT.

Instant Checkout is built on the Agentic Commerce Protocol (ACP), a standard that enables ChatGPT (the “agent”), your shoppers, and your business to communicate with each other to discover products, check out, and fulfil orders.
