Get the TNZO token balance for a hex address. Returns the balance in wei.
AI agents call get_balance to retrieve information from Tenzro Ledger MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
