Thank you very much for the quick answer. I had tried using doh-client 
btw, which did not work behind a proxy.

I ended up using python to get the string I needed.
That's the start of it:

#!/usr/bin/env python3
import requests

proxies = {
  "http": "http://10.10.10.10:8000",
  "https": "http://10.10.10.10:8000",
}
url='https://cloudflare-dns.com/dns-query?name=current.cvd.clamav.net&type=TXT'
headers = {'accept': 'application/dns-json'}

requ = requests.get(url, headers=headers, proxies=proxies)
workstring = requ.json()['Answer'][0]['data'].replace('"','')
print(workstring)
