Free ACP Readiness Checker
Check if your store is ready for ChatGPT Shopping. 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 Shopping).
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. ACP enables fully automated server-to-server transactions between ChatGPT merchant apps 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 Shopping and merchant app integration.
Platform Detection
Identifies your e-commerce platform (Shopify, WooCommerce, BigCommerce, etc.) and checks eligibility for ChatGPT Shopping integration.
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 Shopping depends on your platform. Shopify and Etsy have built-in integrations. 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 build a ChatGPT merchant app.
Build Your ChatGPT Merchant App
Create a dedicated shopping experience within ChatGPT. Implement the five ACP checkout endpoints (create, get, update, confirm, cancel) to power transactions.
Integrate Stripe or PayPal
Set up delegated payments via Stripe Shared Payment Tokens or PayPal so ChatGPT can process payments securely.
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 powering ChatGPT shopping — merchant apps and merchant-site checkout. Payment via Stripe SPT or PayPal. Shopify/Etsy have built-in integrations. Other platforms apply at chatgpt.com/merchants.
UCP (Google + Shopify)
JSON manifest at /.well-known/ucp plus transport APIs. AI agents discover and parse your profile. Supports any payment method. Used by Google AI Mode, Gemini, YouTube Shopping, and Microsoft Copilot.

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. It's a server-to-server REST API built around five checkout endpoints, and the April 2026 spec release added carts, a public product feed spec, orders, delegated authentication, and MCP transport. Since March 2026, ChatGPT focuses on product discovery, with purchases completing on merchant-owned sites or through dedicated ChatGPT merchant apps (like Target, DoorDash, Instacart) — all powered by the same ACP protocol underneath.
How is ACP different from UCP?
UCP (Universal Commerce Protocol) by Google and Shopify starts from a 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 (it gained its own /.well-known/acp.json discovery document in April 2026). UCP powers Google AI Mode, Gemini, YouTube Shopping, and Microsoft Copilot; ACP powers ChatGPT. The protocols are converging structurally, and merchants who want full AI agent coverage increasingly support both.
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?
Stripe is the primary payment partner for ACP, using Shared Payment Tokens (SPT) for delegated payments. When a customer checks out through a ChatGPT merchant app, Stripe generates a shared token that lets the merchant charge the customer without receiving their raw card details. PayPal has also joined as an ACP payment partner, but Stripe remains the easiest integration path.
What happened to ChatGPT Instant Checkout?
It was narrowed, not killed. In March 2026, OpenAI deprioritized inline Instant Checkout: ChatGPT now focuses on product discovery, and purchases complete on the merchant's own site (in-app browser or browser tab) or through dedicated ChatGPT merchant apps like Target, DoorDash, and Instacart. The ACP protocol still powers these transactions — and had its biggest spec release (carts, product feeds, orders, MCP) in April 2026, after the pivot. Feed quality and ACP readiness still decide whether ChatGPT surfaces your products at all.
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.
