Tango: The API for U.S. Government Contracting Data
Tango offers a unified interface for SAM.gov, USAspending, FPDS, Grants.gov, and more. Built for an excellent developer experience at an affordable cost.
Stop stitching together broken data sources
Tango provides a unified API for federal procurement data. Tango is built by govcon experts and software developers who understand the pain of stitching together multiple government data sources. Designed specifically for public-sector builders and for AI-ready data consumers.
Unified Government Data
Tango normalizes messy federal data sources into consistent, developer-friendly models.
Real-Time Opportunity Data
SAM.gov opportunities are refreshed every 20-60 minutes, and are modeled as true opportunities, not just notices.
Unified Contracts, IDVs, Vehicles, and OTAs
Contracts, IDVs, Vehicles, subawards, OTAs, and entities — properly modeled into the way that people actually want them.
Built for Developers
Modern REST API, well-documented schemas, fast search, SDKs for Python & Node.
Fast Search & Filtering
Full-text search, smart filters, strong pagination, and predictable queries.
Shaped Responses
