## 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 x402stock-xyz-e11c2a5b
```

Example prompt: What's the latest US inflation reading — give me the headline CPI-U and core CPI index levels, their year-over-year changes, and a few months of recent history from the BLS.

## When to prefer this

Use this endpoint when you need current US CPI inflation data (headline and core) with year-over-year changes and monthly history without an API key or separate data subscription. Ideal for macro-aware stock analysis, economic commentary, or any workflow needing BLS CPI figures on demand via a simple pay-per-call model in USDC.

## Known failure modes

- Payment failure: x402 payment of 0.02 USDC not completed — request blocked
- BLS data unavailable: upstream BLS source temporarily unreachable
- Stale data: BLS has not yet published the latest month's report
- Rate limiting: too many requests in a short window

## How this service works

US consumer price inflation from the Bureau of Labor Statistics: the latest headline CPI-U and core (ex food and energy) index levels with year-over-year percent change, plus recent monthly history. No ticker needed. Use for macro-aware analysis without leaving for a separate data source. Sourced from US BLS. From x402stock, a market & economic data API (x402, USDC).
