**APIs profiled:** 2

The Bureau of Labor Statistics (BLS) Public Data API provides developers programmatic access to the full catalog of official federal labor and economic statistics published by the U.S. Department of Labor. The API delivers historical time-series data spanning employment, unemployment rates, Consumer Price Index (CPI), Producer Price Index (PPI), wages and earnings, and productivity metrics drawn from major BLS surveys. Two versions are available: an unauthenticated Version 1.0 suitable for lightweight exploration and an enhanced Version 2.0 that requires free registration and returns richer results including catalog metadata, statistical calculations, and annual averages. Responses are served in JSON format, and the API is freely available to the public with no cost for access.
