Use for market research and identifying government contracting opportunities.usa_recipient_profile — Answer "what federal contracts did [company] win recently?" and get a contractor's federal contract awards. Dates are optional and default to the last 12 months; the response always states the window used.usa_spending_trends — "How has [agency] contract spending trended over the last N fiscal years?" / "is [agency] spending on X growing?" / "federal spending history for [topic]" — US FEDERAL contract/award spending over time from USAspending.gov, grouped by fiscal year, quarter, or month. Filter by keywords or by federal agency (DHS/Homeland Security, DOD/Defense, HHS, VA, DOE, NASA, State, Treasury). Returns the historical dollar amount per period for trend and budget-forecasting questions. Federal only — for state & county award data use gov_contracts_search.usa_expiring_awards — Federal contracts EXPIRING soon -- the recompete calendar. "Which VA IT contracts over $10M expire in the next 12 months?" / "what is up for recompete at DHS next year" / "find follow-on opportunities in NAICS 5415" / "whose contract is ending". Returns the incumbent holding each award, its period of performance, obligated dollars, agency, NAICS/PSC, and a usaspending.gov link. Filter by agency, sub-agency, NAICS or PSC prefix, incumbent name, and minimum obligated dollars. Covers awarded CONTRACTS already held by a vendor; for open solicitations still accepting bids use samgov/govcon tools.usa_incumbent_profile — Federal contract portfolio for one contractor -- "what does Leidos hold and when does it expire", "which of Booz Allen's contracts come up for recompete", incumbent research before a bid.
