BuyWhere

BuyWhere is a product discovery and commerce infrastructure platform that helps shoppers and AI-powered applications compare products and prices across retailers in Singapore and the United States. Its catalog covers more than 370 million products from over 900,000 merchants, with search results ranked to reflect location and product deliverability. Shoppers can explore comparisons, current deals, and products across categories including electronics, laptops, smartphones, home and living, fashion, and health and wellness.

For developers, BuyWhere provides a REST API and MCP server for product search, price comparison, and merchant handoff. Structured product and merchant data is designed for AI agents, with availability labels and location-aware ranking to help identify relevant purchasing options. The platform also offers documentation and integrations for agent-building workflows. Merchants can submit product feeds or have existing catalog sources ingested, while commerce partners can collaborate on attribution, referrals, and demand routing. BuyWhere describes itself as a neutral layer connecting merchant catalogs with AI-driven shopping demand, routing interested buyers to retailers through attributed links.
