Free ACP Readiness Checker
Check if your store is ready for ChatGPT Instant Checkout. Test your ACP (Agentic Commerce Protocol) readiness — platform detection, Stripe integration, policy pages, and HTTPS in seconds.
ACP Readiness Checker
Check if your store is ready for OpenAI's Agentic Commerce Protocol (ChatGPT Instant Checkout).
What is ACP (Agentic Commerce Protocol)?
The Agentic Commerce Protocol (ACP) is an open standard created by OpenAI and Stripe that lets AI agents — primarily ChatGPT — complete purchases on behalf of users. Unlike traditional checkout flows where users fill out forms, ACP enables a fully automated server-to-server transaction between ChatGPT and your store.
What Does the ACP Checker Test?
Our ACP readiness checker evaluates your store across four categories that determine your eligibility for ChatGPT Instant Checkout.
Platform Detection
Identifies your e-commerce platform (Shopify, WooCommerce, BigCommerce, etc.) and checks auto-eligibility for ChatGPT Instant Checkout.
Stripe Integration
Detects Stripe payment infrastructure on your site — required for ACP's Shared Payment Token (SPT) flow.
Policy Pages
Checks for required policy links: terms of use, privacy policy, and return policy — all mandatory for ACP merchant registration.
HTTPS & Security
Verifies HTTPS with valid TLS certificate — a hard requirement for all ACP server-to-server API calls.
How to Become ACP Ready
Getting your store ready for ChatGPT Instant Checkout depends on your platform. Shopify and Etsy merchants are auto-eligible. Everyone else follows these steps:
Apply at chatgpt.com/merchants
Register your store with OpenAI's merchant program to get API credentials and access to ACP documentation.
Implement ACP Endpoints
Build the five checkout endpoints (create, get, update, confirm, cancel) plus delegate_payment on your server.
Integrate Stripe SPT
Set up Stripe Shared Payment Tokens so ChatGPT can process payments without exposing card details.
Submit Product Feed
Submit your product catalog via chatgpt.com/merchants. Products need titles (≤150 chars), descriptions (≤5000 chars), GTINs, and pricing.
ACP vs UCP — What's the Difference?
Both ACP and UCP enable AI agents to shop at your store, but they work differently and target different ecosystems.
ACP (OpenAI + Stripe)
Server-to-server REST API. ChatGPT calls your endpoints directly. Payment via Stripe SPT. Shopify/Etsy auto-eligible. Apply at chatgpt.com/merchants for other platforms.
UCP (Google + Shopify)
Static JSON manifest at /.well-known/ucp. AI agents discover and parse your profile. Supports any payment method. Used by Google AI Mode and other agents.

Frequently Asked Questions
What is the Agentic Commerce Protocol (ACP)?
ACP is an open standard created by OpenAI and Stripe that enables AI agents like ChatGPT to complete purchases on behalf of users. Unlike UCP (which is a static JSON profile), ACP is a server-to-server REST API with five checkout endpoints (create_checkout, get_checkout, update_checkout, confirm_checkout, cancel_checkout) plus a delegate_payment endpoint. Merchants integrate via Stripe Shared Payment Tokens (SPT) so customers can pay through ChatGPT without sharing card details with every merchant.
How is ACP different from UCP?
UCP (Universal Commerce Protocol) by Google and Shopify is a static JSON manifest at /.well-known/ucp that AI agents discover and parse. ACP (Agentic Commerce Protocol) by OpenAI and Stripe is a server-to-server REST API where ChatGPT calls your backend endpoints directly. UCP is like a storefront sign; ACP is like a private checkout counter. Both aim to enable AI commerce, but they work very differently and target different agent ecosystems.
What does the ACP readiness checker test?
The checker evaluates four categories: Platform Detection (whether you run Shopify, WooCommerce, or another supported platform), Payment Infrastructure (Stripe integration on your site), Policy Pages (terms of use, privacy policy, and return policy — required by ACP), and Security (HTTPS with valid TLS). Each category is scored and combined into an overall ACP readiness grade from A to F.
Do I need Stripe for ACP?
Yes. ACP uses Stripe Shared Payment Tokens (SPT) as the payment mechanism. When a customer checks out through ChatGPT, Stripe generates a shared token that lets the merchant charge the customer without receiving their raw card details. If you don't use Stripe, you'll need to integrate it before becoming ACP-ready.
Which platforms are auto-eligible for ChatGPT Instant Checkout?
Shopify and Etsy merchants are auto-eligible for ChatGPT Instant Checkout — OpenAI has direct platform integrations, so these merchants don't need to implement ACP endpoints themselves. All other platforms (WooCommerce, BigCommerce, Magento, custom builds) need to apply at chatgpt.com/merchants, implement the five ACP checkout endpoints, and integrate Stripe SPT.
Is the ACP checker free?
Yes, the ACP readiness checker is completely free with no signup required. You get a full readiness assessment covering platform detection, payment infrastructure, policy pages, and security. For continuous monitoring and historical tracking, check out our Pro plans.
