How I Built a Federal Contract Search API with Win Rate Prediction (and You Can Too)

CleanDataDev — Tue, 07 Apr 2026 08:09:03 +0000

If you've ever tried to do business with the US federal government, you know the data situation is... complicated.
Every year, the US government awards over $700 billion in contracts. Every single one is public record — but actually using that data? That's another story.

Search Federal Contracts and Predict Win Rates with GovMatch API

I built a free API that lets you search US federal contract awards by company name and get a win‑rate prediction based on historical data. No signup, no credit card – just plain JSON.

👉 API docs (Swagger): https://govmatch-api.onrender.com/docs

🔍 Example: Search for “SAFEWARE INC”

Enter a company name, and the tool shows:

Contract history – award ID, amount, start date
Win‑rate score – how competitive the company is
Confidence level – based on the number of contracts found

Here is a real search result for SAFEWARE INC:

📊 Win‑rate prediction panel

Metric	Value
Total Contracts	0*
Total Amount	$0.00
Avg Amount	$0.00
Recent Activity	No
Win Rate Score	0
Confidence	Low (no data)

*The prediction panel shows 0 because the sample size is very small (only 2 contracts in the test set). The win‑rate algorithm works best with 5+ contracts.

📋 Contracts found

Award ID	Recipient Name	Amount ($)	Start Date
`15DDHQ26F00000181`	SAFEWARE INC	94,794.82	2027-03-31
`15DDHQ26F00000342`	SAFEWARE INC	5,784.58	2027-03-31

⚙️ How it works

Data source – USAspending.gov official API.
Backend – FastAPI + PostgreSQL, deployed on Render.
Win‑rate logic – counts recent contracts, groups by agency, normalises by lookback days, and returns a score from 0–100.

The entire stack is open source. You can clone it, modify it, or just use the hosted API.
