Which stores let AI agents buy?

AEON's October 21, 2026 post says the person gives a destination, dates, guests, and budget. The agent searches hotel stays on Travala and books after the person selects a stay. The agent wallet is on-chain. The person can fund it and see a record of spending. The post does not name a country, a waitlist, or which agents can use it. AEON said an earlier version already let agents shop on large online stores.

Agentcard's page calls this OpenRouter for commerce. It does not say the stores agreed to the integration, and the 5,026 count is the company's own. This is a developer endpoint, not a shop a person opens. Founder Karen posted the launch on Hacker News on October 30, 2026 (https://news.ycombinator.com/item?id=50304532).

Cloudflare's October 21, 2026 post says WebMCP is still an experimental browser standard, available behind Chrome flags, in Chrome Origin Trials, in some agentic browsers, and in developer tools. Merchants can turn it off. The agent does not take payment. Eligible B2C and B2B stores also expose server-side Storefront MCPs for agents that connect from outside the browser. Commerce.com said no code changes are required (https://blog.cloudflare.com/webmcp-commerce/).

Cafe24's October 22, 2026 newsroom post says this is on for every store built with its solution, with no extra development or integration, and that it is the first Korean commerce platform to apply WebMCP. It lists 11 functions, including product search and details, options and quantity, cart changes, moving to the order form, and order lookup. It works in ChatGPT desktop's built-in browser. Chrome needs a WebMCP extension and developer settings to try it. The shopper logs in and makes the final payment. Cafe24 said WebMCP is still being discussed in a W3C community group, with Google and Microsoft taking part. The official post is in Korean. Cafe24 also said it earlier released an app in OpenAI's Apps in ChatGPT.

CNBC is reporting OpenAI's statements. This tracker did not open a matching OpenAI blog post for the March 24 change. Etsy, Instacart, Target, and Shopify still describe their own ways to buy from ChatGPT. Read those rows before assuming nothing can be purchased there. On October 22, 2026 Cafe24 said WebMCP on its stores works in ChatGPT desktop's built-in browser for search, cart, and the order form, and that the shopper logs in and pays. On October 8, 2026 Newegg said shoppers can add its app from the ChatGPT directory for a live catalog, pricing, and deals. That release does not say payment finishes inside ChatGPT.

Crossmint said the toolkit is live and self-serve as of October 8, 2026. It picks Shop Pay, the Universal Commerce Protocol, or browser checkout depending on the store. Cards that are not eligible for those network programs still check out from Crossmint's vault. This is a developer toolkit, not a shop a person opens directly.

The November 4, 2026 direct checkout in Canada, powered by the Universal Commerce Protocol (UCP), is rolling out, so not every shopper may see it yet. A simpler UCP setup in Merchant Center starts next year, and loyalty rewards are planned later. The Globe and Mail says the Canada launch is one item at a time (https://www.theglobeandmail.com/business/article-google-gemini-ai-shopping-instant-checkout-feature/). The October 15, 2026 post says Universal Cart in the United States names Nike, Sephora, Target, Ulta Beauty, Walmart, Wayfair, and many Shopify merchants, and the merchant remains the seller (https://blog.google/products-and-platforms/products/shopping/universal-cart-launch/). On October 8, 2026 Newegg said eligible U.S. products can be bought in AI Mode and Gemini with Google Pay.

This is Instacart's December 8, 2025 announcement, which says checkout uses the Agentic Commerce Protocol and Stripe. In March 2026 OpenAI said it was moving away from the first Instant Checkout and toward retailer apps. This tracker did not find a later Instacart notice confirming the checkout is unchanged.

Meta's help center says purchasing ability varies by location, merchant, and checkout, and that Muse can also pay by logging in with a saved card. At Connect on September 23, 2026 Meta said more store connectors were being added and that Expedia was coming soon for travel planning. On October 28, 2026 Shopify said Shop Pay checkout is inside Muse, the buyer stays in control, and the card is never shared with the agent (https://www.shopify.com/news/fall-26-edition-merchant). The edition page says shoppers approve purchases before they check out with Shop Pay in Muse (https://www.shopify.com/editions/fall2026).

Shopify says merchants can turn direct Copilot checkout on or off. Target separately says its own guests can buy inside Copilot and use Target Circle benefits there.

CryptoBriefing said on October 29, 2026 that Whop joined PayBox Markets and that the integration is live. Whop merchants do not change their storefronts. PayBox's post the same day says the buyer sees the item, total, payment method, and recipient before money moves. A person can require approval on every transaction or let the agent act within limits they set. PayBox says it is a product of Launchpad Limited, an unregulated MoonPay group entity, for eligible users, and not available in every jurisdiction (https://cryptobriefing.com/moonpay-whop-ai-agent-payments/).

Natural's October 29, 2026 release says Direct is available today to customers with a funded wallet. Mailed paper checks, international wires, and more are coming soon. Natural says it is not a bank. Wallet accounts and banking services are provided by Column N.A., Member FDIC.

The September 15, 2026 availability list says the Google catalog feed is generally available now and UCP checkout is "GA October 2026." Salesforce's developer guide says the integration is generally available in B2C Commerce 26.9 and later, for en-US sites only, and that merchants still join Google's UCP waitlist before Google checkout (https://developer.salesforce.com/docs/commerce/b2c-commerce/guide/ucp-index.html). The innovations page still labels it "GA Oct '26," not "GA Now" (https://www.salesforce.com/commerce/innovations/).

Claude Duet, Grok Bot, and Instinct also offer Shop Pay for brands not on Shopify. For those purchases, Shop Pay uses tokens from Mastercard, Visa, and Discover. American Express tokens are coming soon and are not generally available yet. The buyer stays in control, and the card is never shared with the agent. The edition page also lists Grok Bot for Shop Pay checkout, and a Catalog API commission for agent builders is early access, not generally live (https://www.shopify.com/editions/fall2026). A browser agent on a Liquid or Hydrogen store can finish checkout once the buyer approves (https://www.shopify.com/news/fall-26-edition-developer). October 27: a Catalog beta can list non-Shopify brands that cannot be bought in Shopify checkout, and in the beta only US shoppers see them.

This balance is launching first in Instinct and rolling out to Instinct users in eligible US regions, with New York coming soon. Link's undated help page says US shoppers who use an agent can fund a USDC balance so an agent can complete some purchases without approval (https://support.link.com/questions/link-balance-faq). The shopper sets a per-purchase cap; above it, approval is still required (https://support.link.com/questions/set-up-a-balance-for-agent-wallet-purchases). Stripe's September 8, 2026 post covers connecting Link to Muse. The wallet also powers Grok Bot and Instinct (https://stripe.com/newsroom/news/stripe-helps-meta-muse-shop-with-link). Not every Stripe merchant accepts agent checkout. On October 21, 2026 Claude Duet can pay with Link after approval via a virtual card.

The Paypers report on November 4, 2026 says the card has launched and is certified for Mastercard Agent Pay. It does not name a public signup page or which companies can apply. It describes company-approved agents making business payments, not a consumer checkout. Online travel agencies are named as an early use, not as a list of live customers.

Shoplazza's October 19, 2026 release says TikTok introduced Buy Direct and Shopping Assistant on October 5 and named Shoplazza as a commerce and payment partner. It does not say which countries or which shoppers can use Buy Direct. Shopping Assistant answers product questions inside TikTok's browser, then checkout still happens on the merchant's website.

CryptoBriefing said the October 29, 2026 integration is live and that Whop merchants do not change their storefronts. PayBox says the buyer can require approval on every transaction or allow the agent to act within limits set in advance, and that this is for eligible users and not every jurisdiction (https://x.com/PayBox/status/2115820823327936940).
