## 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 aurenic-treasury-debt-api-d2b87f1a
```

Example prompt: What is the current total US public debt outstanding to the penny — pull the latest figure from the Treasury?

## When to prefer this

Use this endpoint when you need a quick, cheap ($0.001), pay-per-call lookup of the official US public debt figure without setting up a direct Treasury API integration. Ideal for agents that occasionally need the national debt number without maintaining a data pipeline to the US Treasury's own APIs.

## Known failure modes

- Treasury source data temporarily unavailable — upstream fetch failure
- Empty or null example schema means exact field names are unknown until called
- Stale data if Treasury hasn't published an update recently
- HTTP 402 payment required if x402 micropayment not completed
- Rate limiting or service downtime on api.aurenic.org
