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

#showdev #webdev #ai #challenge

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 API credits 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.

{
  "mcpServers": {
    "buywhere": {
      "url": "https://api.buywhere.ai/mcp"
    }
  }
}

Drop that into Claude Desktop, Cursor, or any MCP-compatible client, and your agent instantly gains access to real product data.

The Challenge

Build an AI agent that uses at least 2 BuyWhere MCP tools:

Tool	Description
`search_products`	Search across millions of products with filters
`get_product`	Retrieve full product details by ID
`find_best_price`	Compare prices across retailers
`list_categories`	Browse 180+ product categories

Your agent can be anything: a shopping assistant, a price comparison chatbot, a deal finder, a product research copilot — any use case that makes commerce data useful.

Why This Is Easy

Add the MCP endpoint to your agent
Make 2 tool calls
You have a working shopping agent

Time to first working agent: less than 1 hour.

Works with any framework: Claude, GPT, Gemini, LangChain, CrewAI, AutoGen, custom MCP clients — no restrictions.
