Enable the Agentic Commerce Protocol (ACP) for any WooCommerce store, allowing "Buy it in ChatGPT" functionality.

Description

This plugin enables any WooCommerce-powered website to participate in the Agentic Commerce Protocol (ACP)—the open standard that powers "Buy it in ChatGPT" and other AI agent-driven checkouts.

Key Features

• Turns Your Store Into an AI-Ready Merchant: Creates all the REST API endpoints required by the ACP, generates a machine-readable product feed, and handles the entire checkout process.
• Connects Directly With ChatGPT: Your products can be surfaced in ChatGPT search results, and users can complete purchases natively within the chat experience.
• Per-Product Control: Choose which products are available for ChatGPT checkout with an easy checkbox on each product edit screen.
• Test Mode: Safely test your integration before going live - test orders are clearly marked and identifiable.
• Bulk Actions: Enable or disable multiple products for ChatGPT checkout at once from the product list.
• Secure, PCI-Compliant Commerce: Utilizes Stripe's secure tokenization for payments, ensuring that sensitive data is handled safely.
• Easy Integration: Works seamlessly with your existing WooCommerce setup with minimal configuration.
• OpenAI Bots Setup Guide: Built-in instructions for configuring your robots.txt to allow OpenAI crawlers.
