Bureau of Labor Statistics
The U.S. Bureau of Labor Statistics (BLS) is the principal federal statistical agency responsible for measuring labor market activity, working conditions, price changes, and productivity in the U.S. economy. BLS operates the Public Data API at api.bls.gov, providing programmatic JSON access to published historical time series across more than 75 surveys — including the Consumer Price Index (CPI), Producer Price Index (PPI), Employment Situation (CES), Local Area Unemployment Statistics (LAUS), Quarterly Census of Employment and Wages (QCEW), Occupational Employment and Wage Statistics (OEWS), Employment Cost Index (ECI), Productivity, Import/Export Price Indexes, and Census of Fatal Occupational Injuries (CFOI). Version 1 is open without registration; Version 2 requires a free registration key and provides higher daily limits, more series per request, longer year ranges, catalog metadata, statistical calculations, and annual averages.
