Proceed with caution

Why: The protocol is real, open, and Stripe-backed (high signal), and the consumer surface reaches ~900M weekly ChatGPT users, but real-world merchant go-live is in the low dozens and OpenAI itself is repositioning the surface — strong direction, weak delivery so far.
Next: Track the ACP spec on developers.openai.com as the de-facto agentic-checkout interface and prototype against the Shared Payment Token + checkout-session endpoints, but do NOT commit platform UX to in-chat checkout given the documented April 2026 pivot to merchant-controlled (Apps/redirect) checkout.
