## 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-inflation-data-2a5ead67
```

Example prompt: Pull the latest US CPI and PCE inflation data from x402stock so I can see where inflation stands right now and how it's trended over the past year.

## When to prefer this

Use this endpoint when an AI agent needs programmatic, pay-per-use access to US CPI or PCE inflation data without setting up API keys or subscriptions. Ideal for autonomous agents that need macro inflation data alongside other x402stock market data in the same session, paying fractionally in USDC.

## Known failure modes

- Invalid or unsupported property parameters return an error
- Payment failure in USDC via x402 results in 402 Payment Required response
- Rate limiting or account issues may block access
- Requests for unsupported date ranges or frequencies may return empty or error responses

## How this service works

Headline and core index with year-over-year percent.

## Output

Returns US inflation data including CPI and/or PCE index values and rates, likely as a time series with dates and readings, covering recent and historical periods for macro analysis.
