Singapore developer builds AI agent for real-time grocery price comparison

By PulseAugur Editorial · [1 sources] ·

A developer in Singapore built an AI agent using BuyWhere's MCP to compare grocery prices across multiple retailers. The agent, written in Python, queried a product catalog of over 370 million items and 940,000 merchants, returning real-time price comparisons in under a second. This approach bypasses traditional web scraping, offering a structured data interface for developers to create price alerts, comparison agents, and integrated shopping assistants. AI
