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 shape as /v1/econ/:series bound to cpi.
