Test Your Store's ChatGPT Readiness in 30 Seconds
ChatGPT can shop now.
OpenAI shipped the Agentic Commerce Protocol (ACP) earlier this year, and ChatGPT's shopping agent is live. Target, Sephora, Nordstrom, Best Buy, and Home Depot are already ACP-integrated. When a user asks ChatGPT "find me a waterproof hiking jacket under $200," those stores show up. Yours might not.
Not because your products are worse. Because your store hasn't been checked for ACP compatibility.
Here's the thing: you might already be ACP-ready and not know it. If you're on Shopify with Stripe payments, HTTPS, and proper policy pages, you could be one product feed away from ChatGPT discoverability. But most merchants haven't checked. They're shipping blind while their competitors show up in AI shopping results.
You can test your store's ChatGPT readiness in 30 seconds. No signup required.
What ACP Actually Checks
ACP (Agentic Commerce Protocol) is the open standard OpenAI and Stripe built so ChatGPT can discover products, delegate payments, and complete purchases on behalf of users. It's Apache 2.0 licensed - not proprietary, not Stripe-only.
The UCPtools ACP Readiness Checker tests four categories:
-
Platform detection (25 points) - Are you on Shopify or another platform with an auto-eligible ACP path, or do you need custom integration?
-
Payment infrastructure (30 points) - Do you have Stripe? It's the easiest path to ACP's Delegated Payment flow. But ACP also supports Adyen, PayPal (announced for 2026), and seller-backed instruments like gift cards and store credit.
-
Policy pages (25 points) - The ACP spec requires linked terms, privacy, and return policy pages. Agents need these to communicate purchase terms to users.
-
Security (20 points) - HTTPS with modern TLS. Required by spec. Non-negotiable.
You get a score from 0-100 and a grade: A (80+), B (60+), C (40+), D (20+), or F. Each failing check comes with a finding code and a specific fix recommendation - not just "you failed," but exactly what to change.
ACP vs UCP: What's the Difference?
This trips up a lot of developers. They're two different protocols, two different AI agent ecosystems:
| ACP (OpenAI + Stripe) | UCP (Google + Shopify) | |
|---|---|---|
| What it does | Payment delegation + product discovery | Full commerce: discovery, browsing, checkout |
| Discovery | /.well-known/acp.json + merchant-submitted product feed | /.well-known/ucp manifest |
| Where agents use it | ChatGPT | Google AI Mode, Gemini, Copilot |
| Checkout | Delegated payment tokens (Stripe SPT) or merchant app | Merchant-hosted checkout endpoints |
| Best for | Getting surfaced in ChatGPT shopping queries | Google AI Mode visibility + full commerce control |
The protocols are converging, not competing. Microsoft Copilot already consumes both. checkout.com data shows merchants with dual ACP + UCP implementation capture 40% more agentic traffic than single-protocol stores. The recommendation for 2026 is increasingly: implement both.
But start with the 30-second check. You might already be ACP-ready.
Why This Matters Right Now
OpenAI's March 2026 pivot didn't kill ACP - it expanded it. Instant Checkout inside ChatGPT was deprioritized (users browsed but didn't complete purchases in-chat), and purchases moved to merchant-owned storefronts. The ACP spec had its biggest release after that pivot (April 17, 2026): public product feeds, Cart capability, delegate authentication with 3DS2, and mandatory idempotency keys.
The bottom line: ACP readiness now determines whether your products surface in ChatGPT at all. The purchase completes on your site, but discovery happens inside ChatGPT. And discovery requires ACP.
The numbers back this up:
- McKinsey projects up to $1 trillion in US agentic commerce by 2030
- Morgan Stanley estimates 126 million AI shopping-agent users by 2030
- The retailers showing up in ChatGPT today - Target, Nordstrom, Home Depot - didn't wait. They integrated early.
Every week your store isn't ACP-checked is a week ChatGPT users are buying from your competitors.
