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

Instead of overwhelming amounts of fields in a response, we can return the responses that match what you actually need.
