Example prompt: Can you pull a trial balance report from Novadyne Ledger as of December 31, 2024 — I need to see all account totals with debits and credits to close out the year?

## When to prefer this

Use this endpoint when you need a point-in-time snapshot of all ledger accounts and need to verify that total debits equal total credits — the core accounting check in a double-entry system. Ideal for month-end, quarter-end, or year-end financial close processes, or any time you need a structured trial balance from a Novadyne-managed ledger.
