Use this endpoint when you need to discover U.S. federal contractor firms by industry (NAICS code) and optionally narrow by state or set-aside program type (e.g., 8a, HUBZone, WOSB). Prefer this over general web search when you need structured, filterable procurement data with micropayment-based access.
