FastBuy AI is the platform that makes your Shopify products discoverable by ChatGPT, Claude, Gemini, Grok, Copilot, and every AI assistant. Customers search, compare, and buy your products entirely inside their AI conversation — with one-click checkout on your Shopify store.
AI Commerce Platform
FastBuy AI is an AI-powered shopping platform built specifically for Shopify merchants who want to reach the growing number of consumers using artificial intelligence assistants to discover and purchase products online. In 2026, millions of shoppers ask ChatGPT, Claude, Gemini, and Grok to find products instead of typing keywords into traditional search engines. FastBuy AI ensures your Shopify store's inventory appears in every one of those AI-powered conversations.
The platform works by securely connecting to your Shopify store through Shopify's official OAuth 2.0 protocol, reading only your public product catalog — titles, descriptions, images, prices, available sizes, colors, and variant information. This product data is then made available through multiple AI integration protocols including the Model Context Protocol (MCP), a JSON REST API, OpenAI-compatible plugin endpoints, and llms.txt discovery files. The result is that when any AI assistant receives a shopping-related query from a user, it can search your inventory in real time, present products with authentic images and current pricing, and generate a direct checkout link to your Shopify store.
Conversational commerce is the fastest-growing channel in ecommerce. Consumers increasingly prefer asking an AI assistant "find me a warm winter jacket under $200" rather than scrolling through pages of search results. When an AI assistant can search FastBuy AI's connected stores, it returns products with images, sizes, colors, and precise pricing — then creates a one-click checkout link. The entire buying journey happens within a single conversation, meaning higher conversion rates and lower customer acquisition costs compared to traditional advertising channels.
By joining FastBuy AI's free beta, your store's products become visible across every AI platform. There is no Shopify app to install, no theme modifications required, no code to write, and no monthly fees during the beta period. You enter your store URL, click to authorize via Shopify OAuth, and your full product catalog is live on AI within seconds.
Unlike Shopify's existing sales channels such as Google Shopping, Facebook Shops, or Amazon, FastBuy AI does not require product feed management, advertising spend, or platform-specific optimization. There are no listing fees, no pay-per-click costs, and no algorithmic ranking to compete against. Every connected store's products are searchable equally when an AI assistant receives a relevant query. FastBuy AI is a neutral, open platform — it serves the best matching products to every AI assistant's users regardless of store size or advertising budget.
Customers complete their purchase on your Shopify checkout. FastBuy AI never handles payments, collects customer data, or takes a revenue share. Orders, customer relationships, and all revenue are entirely yours. We simply bridge the gap between your product catalog and the AI assistants that millions of consumers use every day.

AI Integration
FastBuy AI serves your products through multiple protocols so every AI assistant can search inventory and create checkout links.
ChatGPT connects via our OpenAI-compatible plugin endpoints. When a user asks to find a product, ChatGPT calls the search API, receives structured JSON with products, images, prices, and variants, then presents them in the conversation.
Search products:
Create checkout link:
Discovery: /.well-known/ai-plugin.json
Claude and any MCP-compatible AI agent connects directly to our Model Context Protocol server using the Streamable HTTP transport (2025-06-18 spec). The server exposes two tools: shop for searching products and checkout for creating purchase links.
MCP endpoint:
Discovery: /.well-known/mcp.json · /.well-known/agent.json
Grok, Gemini, Microsoft Copilot, and any AI agent can use either the JSON API or MCP endpoint. The JSON API requires no authentication and returns structured product data immediately. AI assistants can also discover capabilities via our llms.txt file.
Quick start — two endpoints, zero auth:
All endpoints are free, unauthenticated, and available 24/7.
Our MCP server exposes two tools with full safety annotations. Both are read-only, non-destructive, and idempotent. Search is powered by dual data sources: our custom AAIP backend runs in parallel with Shopify's native Storefront MCP on each connected store for maximum product coverage and reliability.

Every Shopify store exposes a free, unauthenticated MCP server at https://{store}/api/mcp with tools for product search, FAQ/policy lookup, and cart operations. FastBuy AI aggregates these automatically for all connected stores.

FastBuy AI implements Google's Universal Commerce Protocol (UCP) — the open standard that enables agentic commerce on Google AI Mode and Gemini. UCP lets AI agents discover products, build carts, and facilitate secure checkout on behalf of users.
Discovery: Our UCP business profile at /.well-known/ucp advertises our checkout and fulfillment capabilities so Google can automatically negotiate services.
Capabilities: dev.ucp.shopping.checkout, dev.ucp.shopping.fulfillment · Version: 2026-01-23 · Transport: REST
When an AI assistant searches FastBuy AI, it receives a structured response containing every product that matches the query across all connected Shopify stores. Each product includes the product title and description, the primary product image URL (served from Shopify's CDN for fast loading), the current price with currency formatting, and a complete list of available variants including sizes, colors, materials, and other options. Each variant includes a unique variant_id that the AI assistant uses to generate a checkout link when the customer is ready to buy.
The checkout link redirects the customer directly to the Shopify store's native checkout page with the selected product variant and quantity pre-loaded in their cart. No FastBuy AI branding, no intermediate pages, no additional steps. The customer goes straight from their AI conversation to the merchant's checkout in a single click.
FastBuy AI implements every major AI discovery protocol to ensure maximum compatibility with current and future AI assistants. Our /llms.txt file provides a human-and-AI-readable description of all available endpoints. The /.well-known/ai-plugin.json file enables OpenAI-compatible plugin discovery. The /.well-known/mcp.json file allows MCP-compatible clients to automatically configure their connection. The /.well-known/agent.json file provides the Agent Protocol discovery format. The /.well-known/ucp profile publishes our Universal Commerce Protocol capabilities for Google AI Mode and Gemini, enabling native checkout sessions via the UCP REST API. Together, these ensure that any AI assistant — whether it exists today or is built tomorrow — can automatically discover and connect to FastBuy AI's shopping capabilities.
Trust & Security
Your store's data is protected by industry-standard security practices at every layer.
We connect through Shopify's official OAuth 2.0 authorization flow — the same protocol used by Shopify's own first-party apps. You control access and can revoke it instantly from your Shopify admin panel.
All data in transit is encrypted with TLS 1.3, the latest transport security standard. OAuth access tokens are encrypted at rest using AES-256. No data is ever transmitted or stored in plain text.
We request only the read_products OAuth scope. We cannot see your customers, orders, financials, discount codes, draft orders, or store settings. Only your public product catalog.
Product data is cached temporarily for performance and refreshed on each request directly from Shopify's API. We do not build a permanent copy of your catalog. Shopper search queries are not logged or stored.
Disconnect FastBuy AI from your Shopify admin at any time. When you revoke access, we immediately stop serving your products. No lock-in period, no data retention, no questions asked.
Our infrastructure runs behind Cloudflare's global edge network with automatic DDoS protection, Web Application Firewall (WAF), and edge caching. Your integration is fast, secure, and always available.
