## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability greeneris-data-us-debt-to-the-penny-dda1f764
```

Example prompt: What is the current US national debt? Give me the 5 most recent daily readings including how much is held by the public vs intragovernmental holdings.

## When to prefer this

Use this endpoint when you need authoritative, up-to-date US national debt figures broken down by public debt and intragovernmental holdings, sourced directly from US Treasury. Prefer this over general web search when you need structured, machine-readable fiscal data with a reliable schema. Especially useful for macroeconomic dashboards, financial research, or monitoring US debt trends over time with a 'since' date filter.

## Known failure modes

- HTTP 402 returned with machine-readable payment quote if USDC payment not provided
- Empty result set if 'since' date is in the future or has no business day data
- Invalid 'limit' parameter (outside 1-100 range) may cause error
- Stale data if queried on weekends or US federal holidays when Treasury does not publish

## How this service works

Total US public debt outstanding from the official Treasury Debt to the Penny dataset (FiscalData API, published every business day ~3pm ET). Query: no params -> latest data point; ?limit=30 (1-100, newest first) and ?since=2026-01-01 (record_date floor) for history back to 1993. Returns per day the debt held by the public, intragovernmental holdings and total, in USD. Cached 6h.

## Output

A JSON object containing a count of records, the data source attribution (US Treasury FiscalData API), and an array of debt records each with record_date, total_public_debt_usd, debt_held_by_public_usd, and intragovernmental_holdings_usd. Records are sorted newest first and updated daily on business days.
