## 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 x402-factory-cpi-inflation-data-bls-monthly-be9a8261
```

Example prompt: What's the latest CPI inflation print from the BLS — did it beat or miss expectations, was it revised from the first release, and when is the next CPI report coming out?

## When to prefer this

Choose this endpoint when you need authoritative, BLS-sourced CPI data with revision awareness (first-release vs latest value), a built-in surprise calculation against market-implied or trend-model expectations, and a structured mini-series — all in a single call. Prefer this over raw FRED API access when you want pre-computed surprise logic and prediction market linkage without building your own data pipeline. Best for trading, macro research, or economic monitoring agents that need inflation data with context, not just a raw number.

## Known failure modes

- FRED/ALFRED data unavailable or delayed — upstream outage returns error or stale data
- Payment not provided or invalid — 402 Payment Required response blocking access
- No surprise data available if expectation source cannot be computed — surprise field returns null
- Series not yet updated after BLS release — may return prior month's print briefly after release day
- Rate limiting or network timeout on upstream FRED API calls

## How this service works

CPI inflation (BLS, monthly): latest print, revisions, surprise — Latest CPI inflation print from the BLS via FRED/ALFRED: first-release vs latest value with a revised flag (revisions never pose as print-day numbers), surprise vs a labeled expectation (market-implied when a matching prediction market exists, else trend-model), next monthly release date, and a 12-observation mini-series. Same…

## Output

Returns a structured JSON object with: the FRED series ID and title, latest CPI print (obs date, headline value, YoY basis, units, first-release value, latest revised value, revised flag), surprise object (actual, expected, difference, expectation source as market-implied or trend-model, detail string, optional prediction market slug and probability), next monthly release date, a 12-observation recent mini-series of date/value pairs, and a revisions array showing first vs latest value for recent observation dates.
