bls-oews-api

Query the BLS Occupational Employment and Wage Statistics (OEWS) API for market wage data by occupation, geography, and industry. Trigger for any mention of BLS, Bureau of Labor Statistics, OEWS, OES, occupational wages, market wages, salary data, wage percentiles, median wage, mean wage, labor market rates, SOC codes, or geographic wage differentials.
