Search open U.S. federal contract opportunities (solicitations, presolicitations, sources sought) from a copy synced from SAM.gov several times a day. Use when you need current government RFPs or bids matching a title keyword, 6-digit NAICS code, small-business set-aside or place-of-performance state. Returns deduplicated JSON: notice ID, title, agency, NAICS, set-aside, posted date, response deadline, state, SAM.gov link and lastSynced. Defaults: last 7 days, 25 results (max 100).
