Enrich a list

Send a list of KVK numbers and get the companies back, in one call.

The problem

A list from an export, a trade fair or a purchasing file has numbers and names, and little else. Looking up each row takes an afternoon, and one call per row is slow.

How it works

  1. Put the KVK numbers in one request.
  2. You get the companies back in the same order, with their fields.
  3. A number we don't know is in there too, with null in the fields. That way you see which rows are still unknown.

The exact shape of the request will be in the docs once the API is live.

POST /v1/companies/enrich
{  "kvk_numbers": [    "00000002",    "00000001"  ]}
{  "companies": [    {      "kvk_number": "00000002",      "name": "Voorbeeld B.V.",      "website": "voorbeeld.nl",      "webshop": false,      "open_vacancies": 2,      "whatsapp": null,      "known": {        "count": 35,        "total": 39      }    },    {      "kvk_number": "00000001",      "name": null,      "website": null,      "webshop": null,      "open_vacancies": null,      "whatsapp": null,      "known": {        "count": 0,        "total": 39      }    }  ]}
Example with fictional companies.

What it costs

You pay per company on the list that we know something about. If we don't know a number, or only know the name and address, it costs nothing. See pricing.
