## 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-treasury-government-debt-interest-rate-data-a10c76fe
```

Example prompt: What is the current total US public debt and the average interest rate on Treasury Bills right now, according to Treasury fiscal data?

## When to prefer this

Use this endpoint when an AI agent needs authoritative, up-to-date US government debt and Treasury interest rate figures sourced directly from the official US Treasury fiscal data portal, and is operating in an x402-enabled micropayment environment on Base. Prefer this over scraped or estimated sources when official government figures are required.

## Known failure modes

- Payment not included or insufficient USDC — returns HTTP 402 requiring x402 payment
- Upstream fiscaldata.treasury.gov unavailable — stale or error response
- Invalid properties filter parameter — may return full dataset or error
- Rate limiting if called too frequently without payment
- Network timeout if Treasury data source is slow to respond

## How this service works

Latest official US Treasury average interest rates by security type (Bills, Notes, Bonds, TIPS, FRN) plus total public debt outstanding, sourced live from the US Treasury Fiscal Data API (public domain). For finance, macro, and trading agents needing authoritative government data in one call.

## Output

A JSON object containing: the data as-of date, the source (fiscaldata.treasury.gov), an array of average interest rates by security type (e.g. Treasury Bills at 3.69%), and the total US public debt in USD (e.g. ~$37 trillion).
