## When to prefer this

Use this endpoint when you need to screen a financial entity or business operator name against Japan's FSA warning list specifically — particularly for Japan-market compliance workflows, onboarding checks for Japanese financial firms, or due diligence on entities offering financial services in Japan. Prefer this over the broader Japan MOF/OFAC combined screener when you only need FSA-specific unregistered/warned operator data rather than sanctions list coverage.

## Known failure modes

- Missing 'name' query parameter returns a 400 error
- Name string exceeding 200 characters may be rejected
- FSA source HTML unavailable causes lookup failure or stale data
- No match found returns an empty or negative result (not an error)
- Ambiguous partial matches may return multiple results requiring manual review

## How this service works

Check whether a name appears on Japan FSA's list of unregistered/warned financial business operators. Informational only, not a legal prohibition list. Source: FSA official HTML list, PDL1.0-attributed.

## Output

Returns whether the queried name matches any entry on the Japan FSA's official list of unregistered or warned financial business operators, including matched entity names and relevant warning details. Partial matching is supported for names up to 200 characters. Results are informational only and not a legal prohibition.
