This seems to be supported in jsreport v3 which wasn't deployed to the jsreportonline yet.
We are working on it, but the migration path is more complex. We should deploy it to jsreportonline in Q2 this year.
(There is no way for you to update on your own in jsreportonline)

Do you have some preview option for API calls? Which for example use watermarking when performing development calls?

There is no such thing, unfortunately.
You can occasionally contact support@jsreport.net to clean your credits during your integration phase.
