## 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-national-debt-latest-treasury-debt-to-the-penny-75b1fd5c
```

Example prompt: What is the current US national debt right now — give me the total, the amount held by the public, and the intragovernmental holdings in exact dollars from the Treasury?

## When to prefer this

Use this endpoint when you need official, authoritative US national debt figures sourced directly from the US Treasury's Debt to the Penny dataset, with exact dollar amounts (not rounded to millions) and a clear breakdown between publicly held debt and intragovernmental holdings. Prefer this over general news sources or financial data aggregators when precision, official sourcing, and daily granularity are required for fiscal dashboards, government debt analysis, or sovereign risk monitoring.

## Known failure modes

- Data may have gaps on weekends and federal holidays when the Treasury does not publish
- The latest observation may be 1-2 business days behind real-time due to Treasury publication lag
- Payment of $0.01 USDC required per call — missing or invalid payment returns 402 error
- If the Treasury upstream source is unavailable, the endpoint may return stale or no data
- Response includes warnings array that should be checked for freshness and revision caveats
