## 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 adh-treasury-rates-us-treasury-average-interest-rates-afcb831e
```

Example prompt: What are the latest US Treasury average interest rates — I want to see what the government is actually paying on its debt right now, broken down by security type, so I can assess the macro interest burden.

## When to prefer this

Choose this endpoint when you need the US government's actual average interest rates paid on outstanding debt (not market yield curves) — especially useful for macro regime detection, assessing fiscal stress, or identifying divergence between coupon-weighted legacy costs and current market rates. Prefer this over raw Treasury yield curve endpoints when you want the true fiscal burden perspective rather than forward-looking market pricing.

## Known failure modes

- Upstream Treasury FiscalData API outage returns error or empty data
- Stale data if the upstream source has not published a new record recently
- Payment failure via x402 if USDC balance is insufficient or wallet not configured
- Rate limiting or quota exhaustion on the upstream free API
