Agent use case: Normalize messy Japanese addresses to ZIP codes

Document v1 · published by Koskamo · updated 2026-10-18

Original source

Get standardized address components and valid postal codes from unstructured input, ensuring data consistency for customer records or shipping logistics without manual cleaning.

The agent receives a list of messy or unstructured Japanese addresses. It uses the search_address tool to normalize the input, handling full-width/half-width characters and hyphens. The agent extracts the standardized prefecture, city, town, and the corresponding postal code. It verifies the output format matches the required schema for downstream processing.

Prompt: Please normalize the following address: '東京都 千代田区 丸の内1ー2ー3 ○○ビル3F'. Return the standardized postal code, prefecture, city, and town name.
