Overview

This API gives you access to Demandbase's data about companies, contacts, and people. You can use it to:

• Look up company details such as name, industry, revenue, number of employees, social media links, and more
• Retrieve or search for contact details (individuals, employees) associated with a company
• Fetch family-tree information, competitor data, or installed technologies for a company
• Access company news articles or logos
• Drill into granular details about a specific contact or person

By connecting to these endpoints, your applications can incorporate high-quality firmographic and demographic data—enabling targeted marketing, lead enrichment, or research workflows.

All endpoints are hosted under the Production base URL:

https://uapi.demandbase.com/data/b2b/v1/

Each endpoint describes possible 400 (Bad Request), 401 (Unauthorized), 403 (Forbidden), 404 (Not Found), etc. responses in the OpenAPI specification.
