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.
