This, that and the other wrote:
The ProofreadPage extension's API is read-only,
and
even then, can fetch only two kinds of data:
* the proofread status of a particular page
* meta-information relating to the ProofreadPage
extension (namespaces and
quality levels)
Having said that, if you go to the edit link you
provided
and click "Show changes" (Εμφάνιση αλλαγών), you will see
the template that the ProofreadPage extension internally
fills out. It should be possible to store the wikitext of
this template in your program and fill in the fields
programmatically, then save the page content using the
API's action=edit.
Thank you! It works. I have more than fifty thousand of
those to create, so doing them by hand was unthinkable.
