## 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 houjin-agentic-jp-japanese-corporate-search-8b047a65 -d '<json body>'
```

Example prompt: Can you search the Japanese corporate registry for 'Toyota Motor Corporation' and get me their official corporate number and registered address?

## When to prefer this

Use this endpoint when you need to look up Japanese corporate records, retrieve official corporate numbers (法人番号), or verify the existence and details of a company registered in Japan. Prefer this over generic web search when structured, authoritative data from the Japanese national corporate registry is required.

## Known failure modes

- No matching companies found for the query — empty results array returned
- Query string in unsupported character set or encoding causes parse error
- Service unavailable or payment not processed — HTTP 402 or 503 returned
- Ambiguous query returns too many results with no single clear match
- Non-Japanese company queried returns no results since database covers JP corporations only

## How this service works

Japanese company search: look up companies in the official JP corporate registry by trade name and/or location. Partial-name match on both the Japanese and registered English name, with width/abbreviation normalization, filterable by prefecture, city, and corporation kind. Returns up to 50 corporations with their 法人番号 and lifecycle status. Dynamic pricing: a base fee plus a small per-result fee.

## Output

A list of matching Japanese corporate records from the national registry, each containing the company name, corporate number (法人番号), registered address, and entity type. Results are filtered by the query string provided.
