GET	/v1/search	Faceted search — country, category, status, legal form, …
POST	/v1/match	Rank LEI candidates for a messy name + address (resolution)
GET	/v1/tree/{lei}	Bounded ownership graph — direct & ultimate parents/children
POST	/v1/batch	Enrich up to 50 LEIs in one call

For agents

Point any HTTP client at the base URL — no key, no signup. Every response carries data_versions and attribution, so an agent always knows the source and freshness.
