Tango provides a unified REST API that aggregates data from all major U.S. federal procurement sources—including SAM.gov, USAspending, FPDS, GSA eLibrary, Grants.gov, and GAO protests—into a single, consistently modeled interface. The service refreshes data every 20–60 minutes for opportunities and twice daily for contracts, offering webhooks, full‑text search, and SDKs so developers can query exactly the fields they need without manual data stitching.

Problem
Federal procurement information is spread across multiple systems such as SAM.gov, USAspending, FPDS, DSBS, GSA eLibrary, Grants.gov, and GAO, each with its own schema and update cadence. Integrating these sources requires extensive data stitching, identifier mapping, and manual maintenance, which slows development and introduces errors.
Solution
Tango offers a single REST API that aggregates and normalizes data from all major federal procurement sources. The platform refreshes opportunities every 20–60 minutes and updates contracts, IDVs, and subawards on a twice‑daily or daily schedule, ensuring near‑real‑time accuracy. Responses are schema‑driven and can be shaped to return only the fields a developer needs, eliminating unnecessary payload. Built‑in webhooks push changes for awards, opportunities, entities, grants, and forecasts directly to a consumer’s pipeline. First‑class SDKs for Python, Node, Go, and Rust simplify integration, while the API’s consistent entity resolution across UEIs, DUNS, and USASpending keys removes the need for manual ID stitching.
Target Audience
Primary users are software developers and data engineers building government‑contracting, grant‑management, or market‑intelligence applications, as well as analysts who need reliable, up‑to‑date federal procurement data.
