Steps to reproduce:

1. from zabbix_utils import ZabbixAPI
2. setup variables for username, password and url or perhaps token
3. call api.login(user=args.username, password=args.password) or similar for token, it works
4. call api.host.get() and it fails.

Result:

If I test this with a Zabbix 6.0 server, it works. If I test it with a Zabbix 7.4 server, it also works. With 7.0, however, it fails. If I hand-craft the JSON, it works everywhere, so something seems to be rather messed up with the API if using the 7.0 LTS version.
