Prepare an ACP checkout endpoint (optional)

ChatGPT does not run in-chat checkout for merchants today (OpenAI retired Instant Checkout in March 2026; shoppers buy on your site). This sets up a sandbox-tested Agentic Commerce Protocol endpoint in front of your WooCommerce store, ready to reference if agent checkout reopens. We run every check and map your shipping options from your own policy page. Use a Stripe restricted key (PaymentIntents + Refunds) rather than your secret key; keys are never shown again and deleted on request (see terms); the results below state whether this server encrypts them at rest.
