Copyleaks SDK is a simple framework that allows you to perform plagiarism scans and track content distribution around the web, using Copyleaks cloud.

With Copyleaks SDK you can submit for scan:

• Webpages
• Local files (see supported files)
• Free text
• OCR (Optical Character Recognition) - scanning pictures containing textual content (see supported files)

You can integrate with the Copyleaks SDK in one of two ways:

1. Download the code from here, compile it and add reference to the assembly.
2. Add CopyleaksAPI NuGet by running the following command in the Package Manager Console

Install-Package CopyleaksAPI

To use the Copyleaks API you need to be a registered user. Signing up is quick and free of charge.

Signup to Copyleaks and confirm your account by clicking the link on the confirmation email. Generate your personal API key on your dashboard under 'Access Keys'.

This code will show you where the textual content in the parameter ‘url’ has been used online:
