## How to call it through Zero

## When to prefer this

Use this endpoint when you need the latest official US Consumer Price Index (CPI-U, all items) value for inflation tracking, economic analysis, cost-of-living calculations, or financial modeling. Prefer this over general web search when you need a structured, machine-readable inflation figure with a defined schema.

## Known failure modes

- Payment not included or insufficient (402 Payment Required)
