One route for eleven registers, and that is the whole point: your code need not know each one's quirks. The trade-off to accept is that a field a register does not publish stays absent — unification harmonises the shape, it does not invent missing data.

Catalogue description, exactly as agents read it:
European company profile by country code and national ID — official company registry data in one unified JSON schema: identity, legal form, status, creation date, head office, VAT, LEI, register link. Live: Norway, Estonia, Latvia, Belgium (KBO, NACEBEL + establishments), Czechia (ARES), Slovakia (RPO), Finland (PRH), Poland (KRS), Switzerland (Zefix, the Swiss company registry); Denmark and UK when enabled; elsewhere via GLEIF (LEI). European company data for KYB and due diligence.
Two-letter ISO country code, then the NATIONAL identifier — whose format changes with every country. See the per-country pages.
A wrongly formatted identifier returns 400 and is not billed — but it costs you a round trip. It is the leading cause of failed calls on the foreign routes.
Dated snapshot from 2026-07-29, truncated to one item per array. It is not live data. The full extract is served free of charge from the samples surface, and the schema from the OpenAPI document.

Price: $0.01. The authoritative amount is the one in the 402 quote returned by the route itself — not this text, which derives from the same grid but is still just a page.
An error response cancels the payment: a 400, 404 or 503 is never billed. An upstream outage closes the route with a 503 rather than serving a degraded response.
