ChatGPT Now Checks Out With Stripe — Here's the API

ChatGPT now completes purchases without leaving the conversation. You type "order my usual," ChatGPT checks out — Stripe processes it. And you can implement the same protocol in your own product today. Stripe and OpenAI co-authored the Delegated Payment Spec. Your backend exposes two endpoints: POST /agent/payment-intent — takes the agent's SPT token, creates a confirmed PaymentIntent, returns client secret. GET /agent/payment-status — returns the intent status. Any AI agent — not just ChatGPT — can call those two endpoints. Payment happens inside the agent session. No redirect, no checkout page, no user abandonment. The agent passes a Shared Payment Token so you never see raw card numbers. Stripe validates scope. Your endpoint confirms. This spec is fully public. Stripe's docs and OpenAI's Delegated Payment Spec are both open. You can ship in-conversation checkout this weekend. Link in bio.
