You can generate a premium dl link via premiumize.me for any supported OCH link (for example uploaded.net).
For more infos see my blog post about this workflow.
How to use?
After importing the workflow, edit the prm Script Filter (double click on the red logo) and add your premiumize.me username and password in the Script textbox on the bottom. By typing prm followed by your <OCH URL> the premium link will be generated. If the link is avaible you can hit enter and the premium URL will be copied to clipboard. If a hoster is not supported, unreachable or if the file is unavailable, the workflow will let you know.
