AI agent compares cross-border prices with 73% click-through rate · 2 sources tracked

By PulseAugur Editorial · [2 sources] ·

This build log details the creation of a cross-border price comparison agent using BuyWhere MCP and OpenAI's Agents SDK. The agent aims to find the cheapest product offers across different regions and currencies, considering factors like stock availability and shipping costs. The log outlines three iterations of the agent's architecture, highlighting the evolution from a naive approach to a more sophisticated multi-region, currency-normalized system that achieves a 1.2–2.4 second response time and a 73% click-through rate. Key learnings emphasize the importance of precise agent prompts, the trade-off between latency and feature completeness, and the ongoing challenge of maintaining data freshness for pricing information.
