Welcome to the Company.info API documentation hub.

Our APIs are designed to help you integrate high-quality B2B company data directly into your own systems, platforms, or workflows—enabling you to automate decisions, reduce manual effort, and deliver better user experiences.

Whether you’re building for sales, marketing, onboarding, or compliance, this documentation provides everything you need to get started quickly and scale with confidence. You’ll find implementation guides, reference materials, and best practices to help you make the most of the Company.info API platform.

Key Information

REST

All APIs in the API Hub follow the REST architectural style.

Base URL

All Company.info APIs are hosted under the following production base URL. This URL prefixes all endpoint paths.

https://api.company.info/

Note: A sandbox environment is planned and will be made available for testing and development purposes. Documentation and access details will follow.

API Consumption Model

API usage is metered on a per-request basis. Depending on the API, some endpoints are billable, while others are free of charge.

For example, in order-based APIs, only the request that places the order is typically billable. Subsequent calls—such as retrieving the result or polling for status—are usually free.

To determine which endpoints are billable, please refer to our pricing page, which outlines the cost per request for each specific API.
