Issue with Error Detection in API

Subject: Issue with Error Detection in API
Hello,
I am using the LanguageTool API to check text, but I noticed that it does not find errors that the online version of the site detects. Can I get assistance with this issue?
I have checked the following points:

The text sent through the API matches the text on the website.
2.
All request parameters are specified correctly.
3.
I have not premium access.
I would appreciate your help.

Best regards,
Dmitry.

The website sometimes has A/B tests running with new models. There’s no guarantee that the results of the API are the same as those of the website.

Thank you.
Is it possible to get the results of the work directly from the online version into my project?

Not sure I understand the question, but if you want to get the exact same results as on the website, but using the API all the time: No, there’s no way to guarantee that.

Thanks. I get it.
