Anti-plagiarism API?

Question

API

Are there any APIs for checking text for plagiarism. I found only content-watch, but their prices are already very crazy.

Answer 1

text.ru if I understood you correctly. Prices depend on your activity and needs. I've been using it for about half a year now.

Answer 2

There are good APIs for checking text in Google:
Plagspotter.com
CopyScape.com (Premium)
For Yandex, you can use the standard search API (we break the text into shingles).
And here: Text.ru, as they say, searches all over the Internet (its own algorithm), by the way, it’s pretty high-quality, it searches very well.
