## When to prefer this

Use this endpoint when you need to enrich or identify a Japanese company from their website domain without scraping Japanese government sites. Prefer this over manual scraping when dealing with Japanese corporate data, due diligence on Japanese companies, or building datasets of Japanese firms from web domains.

## Known failure modes

- Domain not found in Japanese public records — returns empty or 404 result
- Non-Japanese domain with no matching Japanese company data
- Rate limiting or payment required if preview quota exceeded
- Malformed domain input causing validation error
- Company data not yet indexed or unavailable in public registries

## 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

Returns structured JSON containing Japanese company profile information associated with the provided domain, sourced from Japan public-data registries — including company name, registration details, and related corporate data.
