Example prompt: Can you look up the legal entity details for LEI 5493001KJTIIGC8Y1R12 — I need its official name, jurisdiction, registered address, current registration status, and whether there are any risk flags?

## When to prefer this

Choose this endpoint when you need authoritative, GLEIF-sourced legal entity data keyed by LEI — ideal for KYB compliance workflows, counterparty verification, onboarding due diligence, or any scenario where you must confirm a company's official identity, jurisdiction, registration standing, or risk posture from a globally recognized source. Prefer over generic company search APIs when you already have the LEI and need structured, compliance-grade output.

## Known failure modes

- Invalid or malformed LEI returns a 400 error
- LEI not found in GLEIF registry returns a 404
- GLEIF data temporarily unavailable returns a 503
- Stale GLEIF data may be returned if provider freshness is low
- Rate limiting or payment failure returns a 402 or 429
