Check validation state of an entry via APIs or get erros via Preview API

If you request content via the cda and this entry has unpubslished links or is simply invalid, you get an errors array with information about the entry.

Is there any way, to get this information, when querying the preview api (the error array seems to be lacking)? Or is there any way to just validate an entry via an API?

I want to use the preview API to provide preview views but also inform, that there are still errors on a page or an entry.
