Production units in CVR-API

A lookup on /api/v1/{cvr} returns the company's production units in the p_units list. Each unit has its own name, address, industry, headcount, contact details and its own protected flag for marketing protection.

{
  "vat": 10403782,
  "name": "VESTAS WIND SYSTEMS A/S",
  "p_units": [
    {
      "p_number": 1017864846,
      "name": "Vestas Wind Systems A/S",
      "address": "Sahara 7",
      "zipcode": 6700,
      "city": "Esbjerg",
      "startdate": "2012-08-17",
      "enddate": "2013-02-13",
      "industrycode": 721900,
      "protected": false
    },
    ...
  ]
}

The list also includes closed units. enddate is set for units that have closed and null for active ones. To keep only the active units:

import requests

company = requests.get("https://apicvr.dk/api/v1/10403782").json()
active = [p for p in company["p_units"] if not p["enddate"]]

for unit in active:
    print(unit["p_number"], unit["address"], unit["zipcode"], unit["city"])
