Build an AI Shopping Agent in <1 Hour — Win API Credits & Get Featured

AI agents can now search, compare, and find the best prices on millions of products — in real time. And you can build one in under an hour.

Introducing the "Build With BuyWhere" Developer Challenge

We are giving away 12 months of free API access plus featured placement to the best AI agent projects built with BuyWhere MCP.

What is BuyWhere?

BuyWhere is a product catalog API built for AI agents. It lets any LLM-powered agent search products across 180+ categories, compare prices, and find the best deals — all through a simple MCP server at api.buywhere.ai/mcp.

The Challenge

Build an AI agent (chatbot, copilot, shopping assistant, research tool, etc.) that uses at least 2 BuyWhere MCP tools:

• search_products — search across millions of products with filters
• get_product — retrieve full product details
• find_best_price — compare prices across retailers
• list_categories — browse 180+ product categories

Why This Is Easy

1. Drop the MCP endpoint into Claude Desktop, Cursor, or your favorite MCP client
2. Make 2 tool calls
3. You have a working shopping agent
4. Polish and ship it

Time to first working agent: <1 hour.
