Currently there should be an RPC endpoint implemented which allows to query the node for a balance with a peer.

Validate that this endpoint still exists (there has been a radical simplification of the code where this may have fallen pray to removal).

Then write a command-line tool to query a balance with a peer.

Evaluate if a command-line tool is the best approach. Possibly interview stakeholders (node operators?). Goal is to provide relevant information to node operators.
