## 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 us-public-debt-outstanding-to-the-penny-7607324e -d '<json body>'
```

Example prompt: What is the current total US national debt to the penny, and how much has it grown over the last 30 days and the past year?

## When to prefer this

Choose this endpoint when you need the official, authoritative US national debt figure sourced directly from the US Treasury Fiscal Data, broken down into public and intragovernmental components, with computed changes over 30 days and one year. Prefer this over scraped or estimated debt figures when precision to the penny and official sourcing are required.

## Known failure modes

- Treasury Fiscal Data API unavailable or delayed — may return stale or null values
- Network timeout from upstream data source
- Malformed request body (wrong bodyType) — returns 400-level error
- Data not yet updated for current date — fecha may reflect prior business day
