# MakeGov

> MakeGov, Inc. builds Tango, a unified API for U.S. federal procurement and assistance data — contracts, IDVs, OTAs, entities, opportunities, forecasts, grants, protests, exclusions, and more, behind a single API key.

This is the marketing site for Tango. For API reference, SDKs, webhooks, and machine-readable docs, start with the Tango documentation llms.txt — it is the primary resource for coding agents integrating against the API.

## Product

- [Tango](https://www.makegov.com/): what Tango unifies and why it exists.
- [About MakeGov](https://www.makegov.com/about.html): the team behind Tango.

Technical notes on federal procurement data and the Tango API, newest first.

- [Some Reasons Scraping Federal Procurement Data Goes Wrong](https://www.makegov.com/blog/scraping-federal-procurement-data.html): Coding agents make it easy to build your own pipeline on SAM.gov and USAspending, and sometimes that's a fine idea. Here are two real records that show where it gets hard, and the case for spending your time and tokens on what you build on top of the data.
- [From a SAM.gov Opportunity to the Federal Register in One Query](https://www.makegov.com/blog/federal-register-by-agency.html): Every SAM.gov opportunity carries an agency code, and the Federal Register has never heard of it. Tango lets you search the Federal Register with the code you already have, so you can see the rules an agency is writing next to what it is buying.
- [New in Tango: State and Local Bids, the Federal Register, Contract Appeals, and More](https://www.makegov.com/blog/new-datasets-august-september-2026.html): In August and September Tango added state and local solicitations, the Federal Register back to 1994, CBCA and ASBCA contract appeal decisions, GSA eBuy requests, Court of Federal Claims protests from PACER, Education and SEC forecasts, SBA Mentor-Protégé relationships, and employee counts and hiring footprints for companies, all behind the same API.
- [What Federal Procurement Data Costs in Tokens](https://www.makegov.com/blog/token-cost-federal-apis.html): Reading one fiscal year of federal contract awards into an LLM costs about $9,400 from the raw USASpending API vs about $3,600 from Tango — the same records, ~2.6x fewer tokens. Here's the benchmark, why the raw payload is so heavy, and how to check it yourself with ttok.
