  The US Bureau of Labor Statistics (BLS) is the principal federal agency responsible
  for measuring labor market activity, working conditions, price changes, and productivity
  in the US economy. BLS provides a Public Data API that enables developers to retrieve
  published historical time series data covering employment, unemployment, inflation,
  wages, productivity, and occupational statistics across all BLS programs. The API
  supports both unauthenticated access (v1) and registered access with higher limits (v2),
  returning data in JSON format for integration into applications, research tools, and
  economic dashboards.

      The BLS Public Data API allows developers to programmatically retrieve
      published historical time series data from all BLS surveys. Version 1 is
      open without registration; Version 2 requires a free API key and provides
      higher query limits (500 daily, up to 50 series per request, 20 years of
      data). The API covers Consumer Price Index (CPI), employment and
      unemployment statistics, wages, productivity, industry employment, and
      occupational statistics. Data is returned in JSON format.
