## 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 japan-company-to-people-enrichment-api-kasanegi-com-c0325b61
```

Example prompt: Can you find the people associated with the Japanese company 'トヨタ自動車' using public registry data? Limit results to 5 and filter by Aichi prefecture if possible.

## When to prefer this

Use this endpoint when you need to identify or enrich people associated with a specific Japanese company using clean, structured access to Japanese public corporate (Houjin) registry data — avoiding manual scraping of government sites. Best when you have a company name (Japanese or romaji) and want structured person-company relationship data for Japan-based entities.

## Known failure modes

- Company name not found in registry — returns empty results or 404
- Ambiguous company name matches many entities — returns up to limit candidates without guaranteed match
- Prefecture filter too restrictive — reduces results or returns empty list
- Invalid limit value outside 1-50 range — returns validation error
- Japanese character encoding issues if romaji name doesn't match registry spelling
- Rate limit or payment failure for x402 callers — returns 402 or 429 error

## How this service works

Stop scraping Japanese government and public-data sites. Call clean Japan payroll, company, and grant APIs over one host. Preview free; one public marketplace listing covers all current products; x402 direct is available for agent-native buyers.

## Output
