Finally we have successfully launched plagiarism checker APIs for all users. As those are HTTP APIs, so you can integrate it with any platform via http requests.
Currently APIs are available for all users (free & premium) but later those will be only accessible for premium users only.
If you are having trouble in understanding how to integrate APIs with your website please let us know and we will integrate it with your business.
You can read out full details about plagiarism checker APIs on the api page.
A complete documentation for using those APIs is available. Check API documentation
