## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability jpverify-japanese-address-normalization-6f8e22a8 -d '<json body>'
```

Example prompt: Can you normalize this Japanese address — '東京都渋谷区道玄坂1-2-3' — and break it out into postal code, prefecture, city, and the canonical address text so I can store it properly in our invoice system?

## When to prefer this

Choose this endpoint when you need to parse or standardize a freeform Japanese address string into structured fields (postal code, prefecture, city, canonical text) for use in Japan-specific invoicing, KYB, contact management, or compliance workflows. Prefer it over generic geocoding APIs when the target locale is exclusively Japan and structured Japanese administrative divisions are required.

## Known failure modes

- Ambiguous or partial address string may result in low-confidence or incomplete parsing
- Non-Japanese or romanized addresses may fail to parse correctly
- Unrecognized locality names may cause prefecture or city fields to be null
- Malformed input (e.g. missing city block numbers) may yield partial results
- Network or authentication errors return non-200 status codes

## Output

Returns structured address components extracted from the input Japanese address string, including the normalized postal code (〒 format), prefecture (都道府県), city/ward/municipality (市区町村), and the canonical full address text suitable for use in company, invoice, and contact records.
