Resolves in both directions
Resolves in both directions: a 20-character LEI returns that entity, a company name returns the matching entities ranked by the search. Each result carries the registered legal name, legal form, jurisdiction, registered address, the local register and registration number, and the LEI registration status with its last update and next renewal date — a lapsed registration means nobody renewed it and the data may be stale, which is stated rather than left to be discovered.
Paid test badge: not yet. The checks above are free: we call the tool without paying and read the payment request it sends back. The Verified badge needs paid calls whose answers match the promised output, and nobody can buy a badge.
