## When to prefer this

Use this endpoint when you need authoritative, multi-source company verification covering global GLEIF LEI data, UK Companies House, or Norwegian Brønnøysund — especially for KYB/KYC, vendor onboarding, contract counterparty checks, or invoice validation. Prefer over generic web search when you need structured legal data including ownership chains, officers, and official registry status in a single call.

- Invalid or malformed LEI (not 20 characters) — returns validation error
- Jurisdiction not supported (only GLEIF global, GB, NO covered) — may return no results
- Ambiguous company name with multiple candidates — returns ranked match list up to the specified limit
- Registry temporarily unavailable — may return service error or timeout
