Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

## When to prefer this

Use this endpoint when you need the current real yield on TIPS instruments for inflation analysis, bond portfolio valuation, or macro dashboards. Prefer over general bond data APIs when you specifically need inflation-protected real yield rates rather than nominal yields.

## Known failure modes

- Data not yet available for the current day — returns most recent prior date
- Upstream Treasury/FRED data feed delay causing stale rates
- Payment failure (402) if USDC balance is insufficient
- Malformed response if the Treasury data format changes
