Endpoint
GEThttps://jp-data-api-production.up.railway.app/research/company-briefWhen to prefer
Use this endpoint when you need a quick, AI-synthesized due diligence or KYB brief for a Japanese, Korean, or UK-registered company, especially when you want official registry data (EDINET, DART, Companies House) combined with a structured Claude-written narrative summary in one call. Prefer this over raw registry scraping when you need human-readable risk notes and filing summaries without manual data assembly.

- Invalid or unsupported country code — defaults to JP or returns validation error

- Ambiguous company name matching multiple entities — may return wrong company
- Claude generation failure — upstream LLM error returns 500
