Company register search (Handelsregister)
Search the official business register for a company by name and resolve its identifiers: find the registration behind a company or trade name and get its register number (KVK number, kvkNummer), RSIN or branch number (vestigingsnummer), with the registered address and whether the registration is still active. The step that turns a company name into the number every other register lookup needs. Zoek een bedrijf op naam, kvk-nummer of adres in het Handelsregister van de Kamer van Koophandel.
price-ascending: candidates are ordered by the listed price of the operation, with no managed-first preference applied. Unlike /v1/apis, this surface does not rank Apiosk-settled listings above federated ones — a comparison that reorders on commercial grounds is not a comparison. Pass sort=managed_first for the catalog's ordering.
