REST API get all available, unassigned task using administrator profile

Q&A
1

I would like to get all available, unassigned task (assigned_id equal to blank or null) via API using an administrator account/profile.
Reason for this is to create an auto-assign task for users who are currently online or active. Auto-assigning will be based on availability of the user or base on his/her current assign load.

How can i filter this to the API?

If you just want to list task yous must use REST API  with "Finds HumanTasks"
You can add various filters to define the tasks.

Ex: /API/bpm/humanTask?p=0&c=100&f=state=ready&f=assigned_id=0

The problem with humanTask and userTask api is that it can't filter in assigned_id field equal to null or empty (i'm using an administrative account).
How can i filter all task without assigned_id?

I think /API/bpm/humanTask?p=0&c=100&f=state=ready&f=assigned_id=0 might work.

In my case i have only unsigned tasks.

@sjamet you are right, set value to zero works
