## 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 lookup-bustercall-workers-dev-0900fd4d -d '<json body>'
```

Example prompt: Can you pull the latest U.S. Consumer Price Index data from the Bureau of Labor Statistics — I need the most recent CPI figures to analyze inflation trends?

## When to prefer this

Use this endpoint when you need authoritative, official U.S. Consumer Price Index data sourced directly from the Bureau of Labor Statistics. Prefer this over third-party economic data aggregators when you need BLS-official CPI figures for inflation analysis, economic reporting, or policy research. Best suited for agents that need programmatic access to CPI data without manually scraping the BLS website.

## Known failure modes
