AI shopping bug exposes currency and locale conflation risks

An AI shopping bug revealed a critical flaw in how AI agents handle currency and location data. When asked to find products for Singapore using Chinese, the AI incorrectly displayed prices in CNY instead of the listed USDC or the expected SGD.

The author proposes a structured data contract to ensure AI agents clearly present authoritative pricing and conversion estimates separately, preventing user confusion and potential transaction errors.
