OnPage API Duplicate Content

‌‌
This endpoint returns a list of pages that have content similar to the page specified in the request. The response also contains data related to page performance and the similarity index that indicates how similar the compared pages are.

The SimHash algorithm is used for calculating the similarity score from 0 to 10, where 0 means that comparative pieces of content are not similar at all, and 10 means they are identical.

Instead of ‘login’ and ‘password’ use your credentials from https://app.dataforseo.com/api-dashboard
