Example prompt: What's the latest US Treasury General Account balance, and has it been building or drawing down over the past 30 days?

## When to prefer this

Choose this endpoint when you need authoritative, cited US Treasury General Account balance data with built-in build/drawdown classification and historical series — particularly for macroeconomic research, fiscal liquidity monitoring, bond market analysis, or government debt ceiling tracking. Prefer this over scraping Treasury.gov directly or constructing your own daily-change logic, as it handles data normalization and classification automatically.

## Known failure modes

- Invalid 'days' parameter (outside 1–3660 range) returns a validation error
- Treasury Fiscal Data source unavailable or delayed may result in stale or missing data
- Requesting future dates or non-trading days may return no data for those periods
- Network or payment authorization failure (x402) returns 402 Payment Required

## How this service works

The US Treasury operating cash balance (the Treasury General Account) from the Daily Treasury Statement. Returns the latest TGA closing balance, the history over a window and the computed daily change flagged as a build or a drawdown. Cited to Treasury Fiscal Data.

## Output

Returns the latest TGA closing balance in USD, a time series of daily closing balances over the requested window (default or specified number of days), the computed daily change for each day, and a classification of each day's movement as a 'build' (increase) or 'drawdown' (decrease), all cited to Treasury Fiscal Data.
