## 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-pce-inflation-data-8aafe322
```

Example prompt: What's the latest PCE inflation reading — both headline and core — including year-over-year change and recent monthly history?

## When to prefer this

Use this endpoint when you need the Fed's preferred inflation metric (PCE) rather than CPI — particularly for monetary policy analysis, Fed rate decision context, or when comparing headline vs core inflation excluding food and energy. Prefer over CPI endpoints when the question is about what the Federal Reserve targets.

## Known failure modes

- FRED data temporarily unavailable — stale or empty response
- Payment not processed — 402 response if USDC not provided
- Network timeout if FRED upstream is slow
- Null values for latest_index or yoy_percent if most recent data not yet released

## How this service works

US PCE (Personal Consumption Expenditures) price inflation — the Fed's preferred inflation gauge — with the latest headline and core (ex food and energy) index levels, each with year-over-year percent change, plus recent monthly history. No ticker needed. Complements the CPI endpoint with the measure the Fed actually targets. Sourced from the St. Louis Fed (FRED). From x402stock

## Output

Returns an object with source (fred), as_of date, series name, unit, headline PCE object (series_id, latest_index, latest_month, yoy_percent), core PCE object (series_id, latest_index, latest_month, yoy_percent), and an array of recent monthly history entries each with date and value.
