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.
Example use cases
Trading desk inflation surprise check
“Pull the latest CPI print and tell me if it was a surprise versus what the market expected — I want to know the actual number, the expectation, and whether we beat or missed.”
Macro research revision tracker
“I'm writing a macro brief — can you get me the latest CPI release and flag whether it was revised from the initial print, and show me the revision history for recent months?”
Economic calendar monitoring
“When is the next CPI report from the BLS scheduled to come out, and what did the most recent print show on a year-over-year basis?”
Technical details
Endpoint
GEThttps://x402-factory.com/v1/econ/cpi?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
