3. FIRST COMMENT (Maker's Story)
Post this immediately when you launch:
Hey Product Hunt! 👋
I'm Wei, founder of BuyWhere.
Here's the problem I kept hitting: building a shopping agent means either scraping retailer sites (hello, bots get blocked) or maintaining fragile parsers that break the moment a retailer changes their HTML.
So I built BuyWhere — a product catalog API specifically designed for AI agents.
What makes it different:
- 500+ retailers, one unified API
- 60-70% fewer tokens in responses (your agents stay within context windows)
- Real-time confidence scores so agents know when to trust the data
- Built-in affiliate links — earn while your agents shop
- MCP server for direct integration with Claude, Cursor, and any AI client
We're live in Singapore and the US with 2M+ products. SEA expansion coming Q3.
Would love your feedback — what's broken, what's missing, what would make this actually useful for your agent projects?
