On November 6, 2026, The Verge reported that Alexa for Shopping can take a text message and a photo, recommend matching Amazon listings, and order on the user's behalf. The Verge said Amazon is rolling texting out to a small group of U.S. customers that day, then to millions more in the coming weeks. It builds on the Alexa for Shopping assistant Amazon already offers.

On November 6, 2026, Cashfree launched Checkout for Agents. WebMCP lets an AI agent read order details and available payment methods without reading the page HTML. Cashfree said it covers every merchant on hosted checkout, with no integration change. The customer still reviews the final order and authenticates payment. Agents cannot enter card details through WebMCP, and a UPI PIN stays in the customer's app. Co-founder Reeju Datta said agents are less than 1% of checkout sessions. Cashfree said this could cut token use by more than 40%, and it did not publish details of that test.

On November 6, 2026, firmly launched Ask Agent, conversational shopping on a merchant's website with natural-language product discovery, a real-time catalog, in-chat checkout, and customer support. The company also said it raised a $15 million Series A led by Squarepoint Capital, with J.P. Morgan Payments, Mastercard, and Samsung NEXT participating. firmly Connect is meant to let merchants sell across AI agents and other channels without merchant engineering. The report does not say how an in-chat payment is authorized.

On November 6, 2026, The Paypers said Sardine launched Know Your Human (KYH) and is seeking design partners (https://thepaypers.com/fraud-and-fincrime/news/sardine-launches-know-your-human-protocol-for-agentic-commerce). Headers pass a device ID, fingerprint, and IP, with email, phone, and KYC in extended cases. Sardine says this targets false declines when a cloud browser looks like a bot. The agent binds the device with Sardine's SDK or a merchant Method URL. A texted link expires after five minutes and can be opened up to three times. KYH complements existing agentic commerce protocols.

Protocol ·
An open standard from Stripe and OpenAI that lets an AI agent send a shopper's order to a store without seeing the card number.
Stripe's current documentation also names Meta as a creator. The public GitHub spec is still marked beta. ChatGPT's first in-chat Instant Checkout, which used ACP, was later narrowed.
Protocol ·
An open way for an agent to pay for a web page or API, often in USDC, after the server replies that payment is required.
June 15, 2026 is the date Coinbase and AWS said publishers on CloudFront could turn x402 on. Coinbase says it incubated the protocol earlier and later moved it under the Linux Foundation. This row does not state an earlier launch date. On October 20, 2026 Mastercard said Agent Pay for Machines builds on x402. In that early-access product, a service can answer with HTTP 402 and the agent signs a payment voucher inside an approved budget. Mastercard named pilots with Cloudflare, Ant International, AIsa, Base, BVNK, Coinbase, and Hype. Coinbase for Agents is a separate product. Its August 21, 2026 changelog entry says agents can trade S&P 500 U.S. stocks, which is not an x402 purchase (https://docs.cdp.coinbase.com/get-started/changelog).
Protocol ·
Google's open payments protocol records what a person allowed an agent to buy, including some purchases the person pre-approves and does not watch.
On April 28, 2026 Google donated AP2 to the FIDO Alliance and released version 0.2. FIDO is still standardizing it. Version 0.2 is not a finished FIDO standard.

Sardine's Know Your Human (KYH) protocol lets an AI shopping agent pass a shopper's device ID, fingerprint, and IP address to a merchant in a few HTTP headers so a checkout from a cloud browser is less likely to be declined as a bot.
The Paypers reported this launch on November 6, 2026 and said Sardine is seeking design partners among agent developers and merchants. Neither source names merchants that have adopted KYH. Sardine says the protocol complements existing agentic commerce protocols. An agent can bind a device with Sardine's SDK or a merchant Method URL. A texted verification link expires five minutes after it is created and can be opened up to three times. Sardine's page calls email, phone, and KYC possible extensions. The Paypers lists email and phone among the identifiers and calls KYC an extended case (https://thepaypers.com/fraud-and-fincrime/news/sardine-launches-know-your-human-protocol-for-agentic-commerce).

An open standard from Google and Shopify so an agent can find products, build a cart, and check out while the store remains the seller.
A protocol release and a shopper-facing buy button are different things. The spec can be live while a particular store's checkout is still a pilot. On October 16, 2026 Shopify said Checkout MCP and Cart MCP support the UCP buyer-consent extension from version 2026-08-25. On October 8, 2026 Newegg said U.S. shoppers can buy eligible products in AI Mode and Gemini with Google Pay. The Shop MCP skill linked from Shopify's October 13, 2026 changelog tells agents to prefer Shop/UCP checkout when it is available. On October 19, 2026 Shoplazza said TikTok Buy Direct uses UCP to connect with merchant systems, and that the brand remains the seller. On October 15, 2026 Google said Universal Cart, powered by UCP, was rolling out in the U.S. in Search and the Gemini app.
Live means a shopper can use it today, sometimes in one country or at selected stores. ChatGPT still helps people find products and open store apps, after OpenAI said the first in-chat Instant Checkout was not flexible enough. 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.
Live means a shopper can use it today, sometimes in one country or at selected stores. Starting November 4, 2026, shoppers in Canada can buy in AI Mode and the Gemini app from lululemon, select Shopify merchants, Shoppers Drug Mart, and Simons with Google Pay, and the retailer stays the seller. In the United States, Universal Cart is still rolling out in Search and the Gemini app. 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.
These are the stores in the tracker.

Walmart (Pilot · not yet live): Not yet live for shoppers. Walmart said Agent Profiles launch in the next month, with a spending limit or approval on every purchase, and the Agent Gateway starts as a developer beta so assistants can search and buy at Walmart and Sam's Club without receiving card data. Newegg (Live): U.S. shoppers can buy eligible Newegg products inside AI Mode in Google Search and the Gemini app with Google Pay, and Newegg is the merchant of record. Etsy (Live): U.S. shoppers can buy from U.S. Etsy sellers inside ChatGPT, which was the first store checkout launched with the Agentic Commerce Protocol. Target (Live): Target says shoppers can buy on Google AI Mode and Gemini, in Microsoft Copilot, and in Target's app inside ChatGPT. Expedia (Live): Expedia shows live flights and hotels inside Claude, then sends the traveler to Expedia to finish the booking. Zalando (Announced · not yet live): Zalando said that from 2027 its own AI agent will buy products from other online shops inside the Zalando app, starting with Westwing home and living goods.

Amazon: Amazon blocks outside AI shopping agents from its store, and Meta's Muse users see a notice that unauthorized AI agent access violates Amazon's terms, while Amazon's own Alexa for Shopping assistant can still buy for a Prime member and Buy for Me can buy some products off Amazon. A separate weekly page reads public robots.txt files for major US retailers. That file is a request, not a lock.
This tracker does not say whether that is safe. Agentic Commerce Protocol (ACP): An open standard from Stripe and OpenAI that lets an AI agent send a shopper's order to a store without seeing the card number. Visa Intelligent Commerce: Visa's Intelligent Commerce Connect pilot gives businesses one integration for agent payments, using tokenized cards and spending limits. Mastercard Agent Pay: Mastercard's program for letting a registered AI agent pay with a tokenized card, with the cardholder setting what the agent may buy. The October 29, 2026 earnings call disclosed a broad OpenAI agreement that includes Agent Pay. The Paypers and PYMNTS do not describe a new shopper checkout. Meta Muse: Meta's Muse agent can shop the web for a connected U.S. shopper and must show the total for approval before it pays.

These are the protocols and network programs behind the tracker. Agentic Commerce Protocol (ACP): ACP is a shared checkout language. An AI agent can pass an order to a business, and the business still owns the sale. Agent Payments Protocol (AP2): AP2 is a way to prove that a person allowed an agent to pay, and to keep a record of what was approved. Universal Commerce Protocol (UCP): UCP is a shared shopping language so an agent and a store can discover products, build a cart, pay, and follow the order afterward. x402 (x402): x402 lets an agent pay for a web request on the spot, usually with a stablecoin, without opening a new account for that site. Visa Intelligent Commerce (Visa): Visa Intelligent Commerce is Visa's program for agent payments: tokenized credentials, spending limits, and a pilot on-ramp called Intelligent Commerce Connect. Mastercard Agent Pay (Mastercard): Agent Pay is Mastercard's program for agent payments, built on tokenization so a registered agent can pay and the cardholder stays in control. Know Your Human (KYH): Know Your Human (KYH) is Sardine's protocol for passing a shopper's device and network identifiers to a merchant when an AI agent checks out, so the merchant can tell that person from a bot.
