Company lookup APIs: LEI and the Nordic registers

Find companies by LEI or name, and look up Norwegian and Finnish company registrations by number. Company-level data only.

The LEI lookup finds a legal entity by its 20-character identifier, or searches by legal name and country, and returns the registry number, legal form, addresses and the status of the LEI registration.

The Nordic lookup reads the Norwegian and Finnish company registers by organisation number, business ID or name: legal form, industry, address, registration date and status. Both return company-level data only, no information about individuals.

The calls

Each call returns 402 with the price until a payment is attached; an x402 client pays and retries automatically. Calls that fail are not charged. See Get started and the guide for bots and agents for code.

Questions

Can I find a company outside the connected registers?

The LEI lookup covers any company with an LEI, wherever it is registered. Dedicated register lookups exist for Norway, Finland, Czechia, Slovakia, France, the United Kingdom and Poland (by number).

Does it return directors or owners?

No. Only company-level data.
