Buywhere MCP Server

BuyWhere API

The product catalog API for AI agent commerce — search, compare, and track prices across 40+ retailers in Southeast Asia and the US.

Overview

BuyWhere is an agent-native product catalog API indexing 5M+ products from 40+ retailers across Singapore, Malaysia, Indonesia, Thailand, the Philippines, Vietnam, and the United States. It is purpose-built for AI shopping agents: BM25-ranked search, structured price comparison, deals discovery, and affiliate link tracking out of the box. The API is MCP-compatible and works with Claude Desktop, Cursor, LangChain, CrewAI, and any MCP-enabled AI client.
