Setup steps: Create a read-only API key in mailcow
In mailcow, open System → Configuration → Access → API and find the Read-only access section.
Tick Activate API, add DumbMonit's IP address to the allowed addresses and save.

Heads-up. mailcow only answers the addresses allowed on its API page: if DumbMonit reaches it through NAT or a relay agent, allow that address instead.
