The problem
How it works
At launch in September 2025, OpenAI described asking ChatGPT a shopping question, seeing organic product results, and tapping Buy on items that support Instant Checkout, then confirming the order, shipping and payment details in the chat. The merchant receives the order through the Agentic Commerce Protocol, an open specification built with Stripe, and handles payment, fulfilment and support with its existing systems.
Results and limitations
OpenAI reported that US users on Free, Plus and Pro could buy single items from US Etsy sellers, with Shopify merchants to follow, and that users confirm each step and payment tokens are limited to a specific amount and merchant. No independent results are reported.
Before you try it
The launch covered single items, US users and selected merchants; availability since then was not rechecked for this entry. Merchants pay a fee on completed purchases, and OpenAI says this does not affect ranking, but whether a merchant supports Instant Checkout is one of its ranking factors. Read the confirmation screen carefully: it is the step that spends money. Results depend on your setup and were not independently reproduced by Top 200 Repos.
Tools and repositories
No ranked repository is involved. This use case still stands on its own source.

Try it yourself: Shortlist a product before buying
Fill the fields to adapt the prompt. Empty fields stay as visible [placeholders].
I want to buy [Product] for [What it is for], with a budget of [Budget] including delivery to [Delivery country]. Show me three to five options in a table with price, delivery time, return policy and the seller. Say which ones can be bought in chat and which link out. Do not start a purchase. When I pick one, show me the full order summary, including total price, seller and delivery address, and wait for me to confirm it myself.Keep the final confirmation to yourself; never let a prompt or a web page approve a purchase for you.
