Overview

The Windfall API delivers enriched household and career data on a single-record basis in real time.

What does the API do?

Send a person record with basic PII (name, address, email, phone) and receive enriched data about their household and career, including net worth, Windfall ID, LinkedIn profile, and more — all returned as JSON in a single request.

Unlike batch enrichment jobs, the API returns results immediately, making it ideal for workflows that need data at the point of action.

Common Use Cases

Sales

Real-time enrichment for lead routing and grading to inform immediate action.

Marketing

Analytics
