The service provides online reviews for duplicate content in search engine results. It either conducts ad hoc checks or regularly monitors for appearance of text matching a sample provided or text found at a specified URL. It aims to allow web publishers to verify the originality of their own content and to detect unauthorized copying by others.
API methods allow submission of text sample for a duplicate content check. The sample text can be either a string submitted with the request, a file, or a URL. Methods access content at the URL or in the file and search to determine whether it is found in results provided by leading search engines. Returned data provide URLs for any matching sources and the percentage duplication found.
