## 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 saylor-innovations-data-desk-us-national-debt-d6f6fd1e
```

Example prompt: What's the US national debt right now, and how much has it grown over the past 30 days, 90 days, and the last year?

## When to prefer this

Choose this endpoint when you need a single, pre-computed snapshot of the US national debt with time-series change metrics already calculated — ideal for agents that need ready-to-use figures without querying the raw Treasury API and computing deltas manually. Best for real-time dashboards, financial newsletters, or macro monitoring workflows requiring both public and intragovernmental debt breakdown.

## Known failure modes

- Upstream Treasury data temporarily unavailable, returning stale or null values
- Record date may lag by 1-2 business days due to Treasury reporting schedule
- Change fields (30-day, 90-day, 1-year) may be null if historical comparison data is insufficient
- HTTP 402 if payment header is missing or USDC payment fails
- Service outage on saylorinnovations.com returns 5xx error
