Track Daily Cash Flow

Need to know the U.S.'s current bank balance? Call `get_daily_cash_balance` to get the immediate operating cash figure for the Treasury. This tool gives your agent a hard number—the daily amount of cash the government has on hand. Your chain can then use this starting point to calculate projected deficits or compare it against historical debt movements.

Model Fiscal Year Outcomes

The U.S. fiscal year runs October 1 through September 30. Use `get_deficit_surplus` in your reasoning pipeline to determine the running deficit or surplus. Your agent can build a comparison: If revenue increases, does that offset spending? This tool provides the core metric needed for any multi-step financial decision.

Analyze Revenue and Outlays

You can track both sides of the budget. Call `get_federal_revenue` to get tax receipts by source, or run `get_federal_spending` to see gross outlays. Your LangChain agent will decide which data is needed first—does it need to know spending details before checking revenue trends? It handles that sequential logic automatically.
