## 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-live-data-db8a5874 -d '<json body>'
```

Example prompt: What is the US national debt right now — total outstanding, how much is held by the public, and how much changed since yesterday?

## When to prefer this

Use this endpoint when you need real-time or near-real-time official U.S. national debt figures (total, public, intragovernmental) with daily granularity, directly from Treasury Fiscal Data, without needing to parse raw government APIs yourself. Prefer it over scraping Treasury directly when you want a clean machine-payable API response.

## Known failure modes

- Treasury upstream API unavailable — stale or no data returned
- Network timeout on the DDG proxy endpoint
- Payment not processed (x402 payment required, USDC not provided)
- Malformed request body causing 400-level error

## How this service works

Total U.S. public debt outstanding, debt held by the public, intragovernmental holdings, the daily change, and recent history. Upstream: Treasury Fiscal Data — Debt to the Penny (public domain).

## Output

Returns total U.S. public debt outstanding, debt held by the public, intragovernmental holdings, the daily change in debt, and a recent historical series — all sourced from the U.S. Treasury Fiscal Data Debt to the Penny dataset.
