About the NetworkCalc APIs

We offer a free REST API to facilitate application development and provide quick access to network information. APIs are also available for managing subnets and domains saved to your NetworkCalc account.

Use the REST APIs to programmatically access our network tools with simple HTTPS interfaces and JSON responses.

This documentation provides example uses for accessing the APIs command-line using Python, cURL (Linux), and PowerShell (Windows).

The NetworkCalc APIs are RESTful APIs oriented around resources such as subnets and domains. They use common HTTP verbs that correspond to the four CRUD operations:

• •
  Create
• •
  Read
• •
  Update
• •
  Delete
