Future of the LanguageTool HTTP API

Hi, if you’re using our HTTP API or are considering it, please check this issue and add your comments: - in a nutshell, I’m suggesting to create a new JSON-based result of what is today XML.

A prototype of a new API is now online and can be tested here: – please provide feedback, this API is supposed to be stable for the next 10 years…

See Announcement: old HTTP API will be replaced for our announcement about the old API being turned off.


What happened to srctext parameter? You didn’t mention it’s deprecated but it’s absent in Swagger.

Hi, seems it was lost. I’ll try to re-add it again later this week.
