## How to call it through Zero

```sh
zero fetch --capability mercury402-tips-rates-current-ee8a9766
```

Example prompt: What are the current U.S. TIPS rates? I need the latest real yields on inflation-protected Treasuries for my macro dashboard.

## When to prefer this

Use this endpoint when you need the latest real (inflation-adjusted) Treasury yields specifically for TIPS instruments, as opposed to nominal Treasury yields. It is ideal for macro research, inflation breakeven calculations, portfolio construction, and economic dashboards. Prefer this over general FRED API wrappers when you need a pay-per-call, agent-friendly endpoint with no subscription setup and USDC-based micropayment access.

## Known failure modes

- Data not yet published for today — Treasury updates rates on business days only; may return previous business day data
- HTTP 402 payment required if USDC payment on Base is not included
- Rate limits or network timeouts returning 5xx errors
- Empty rates object if Treasury data feed is temporarily unavailable
