How this service works
Core CPI inflation (BLS, monthly): latest print, revisions, surprise — Latest Core 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…
Output
Returns a JSON object with: the FRED series ID and metadata (title, units, frequency, source agency, release name); the latest print (observation date, headline value, units, basis, first-release value, latest revised value, and a revised boolean flag); a surprise object with actual, expected, and surprise delta plus the expectation source (market-implied or trend-model) and any linked prediction market; the next scheduled release date; a 12-observation recent mini-series; and a revisions array showing first vs latest values per observation date.
Example use cases
Pre-Fed-meeting inflation briefing
“Pull the latest Core CPI number from the BLS, tell me whether it surprised to the upside or downside versus market expectations, and flag if the previous month's reading was revised.”
Inflation trend monitoring dashboard
“Give me the Core CPI readings for the past 12 months along with the next scheduled release date so I can update my inflation tracker.”
Economic research revision analysis
“I need to compare the first-release Core CPI values against their current revised values — can you pull the full revision history and flag which months were revised?”
Technical details
Endpoint
GEThttps://x402-factory.com/v1/econ/core-cpi?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need the official BLS Core CPI figure with full revision transparency (first-release vs latest), a quantified surprise metric grounded in either market-implied expectations or a trend model, and a ready-made recent time series — all in a single call. Prefer this over raw FRED API access when you want pre-computed surprise, revision flagging, and next-release scheduling bundled together without extra processing.
Side effects
- FRED/ALFRED data temporarily unavailable — upstream outage returns a 5xx error
- No surprise data available if no prediction market exists and trend model fails — surprise field returns null
- Payment not received (x402 protocol) — request blocked before data is returned
- Stale data if BLS has not yet published the latest monthly release — returns most recent available print
- Malformed query params — though this endpoint takes no required params, unexpected fields are ignored
