## When to prefer this

Use this endpoint when you need to verify whether a specific crypto-asset exchange or business is officially licensed by Japan's FSA. Prefer this over generic web search when you need a structured, authoritative result from the FSA's own license list. Best suited for compliance screening, due diligence, or user-facing verification of Japanese crypto businesses.

## Known failure modes

- Name not found in FSA list — legitimate unlicensed or misspelled entity
- Ambiguous fuzzy match returning multiple possible results
- FSA list may not be real-time; very recently added or removed licenses may not be reflected
- Query string too long (>200 chars) causes validation error
- Empty name parameter causes bad request error
