Why BuyWhere?

BuyWhere is a product search API for AI agents. We aggregate 11M+ products from Singapore, Southeast Asia, and US markets into a single, agent-friendly interface — no store management, no Shopify integration. Just search and compare products in real time.

• One API — all markets, all retailers
• Agent-native — built for MCP from day one
• Real-time — live pricing and availability
• Developer-first — no SDK needed, just add the server

A2A Protocol

BuyWhere also supports the Agent-to-Agent (A2A) protocol for multi-agent task delegation. View our Agent Card at /.well-known/agent.json.
