BLS Public Data API (Version 2.0)

BLS Public Data API (Version 2.0) is a rest api from U.S. Bureau of Labor Statistics providing finance & macro data. The official U.S. government REST/JSON API for Bureau of Labor Statistics time series — CPI, nonfarm payrolls, the unemployment rate, JOLTS, PPI and more. Because BLS is the literal resolution source for Polymarket/Kalshi CPI and jobs-report markets, bots poll it the instant new numbers post on release day to settle or trade ahead of the crowd.
