Welcome to the Company.info API Documentation Hub.

The Company.info APIs allow you to integrate reliable business data directly into your applications, platforms, and workflows. This enables you to automate data-driven processes and use Company.info data at scale.

This section explains the fundamentals of the API platform, including authentication, API standards, usage, and integration best practices.

Platform fundamentals

REST

All APIs in the Company.info API Hub follow REST principles and use standard HTTP methods and status codes.

🔗 Base URL

Use the following production base URL for all API requests:

https://api.company.info/

The endpoint paths shown throughout the documentation are relative to this base URL.

Usage and billing

API usage is measured per request. Whether a request is billable depends on the API, endpoint, and applicable agreement.

For order-based APIs, for example, placing an order is generally billable, while retrieving the previously ordered result is generally not billed again.

Refer to the documentation for the relevant API to determine which operations are billable.

Getting Started

Explore the APIs

Start with the functional documentation to discover the available APIs and determine which products support your use case.

Each API section explains its purpose, primary workflow, and available functionality.

Obtain an API key

Company.info uses API keys to authenticate requests. Your API key must be included in the request headers when calling an API.

See Authentication for instructions and security recommendations.

Understand JSON

Company.info APIs use the JSON format to provide consistent request and response structures.

Review our JSON guidelines for information about resource objects, attributes, relationships, errors, and pagination.

Some endpoints may return a different media type when the requested resource is a document, file, or other non-JSON resource. The relevant API reference describes these exceptions.

Make your first request

Select an API from the navigation menu and open the corresponding API reference. Each endpoint includes its required parameters, request and response formats, possible errors, and available examples.

Use your API key and the production base URL to send your first request:

curl --request GET \
  --url 'https://api.company.info/{endpoint}' \
  --header 'Accept: application/vnd.api+json' \
  --header 'X-API-Key: your-api-key'
