How to prevent using a Resource if 0 available?

Is there any way to use token-mod or chatsetattr to check the resource value and stop the script or macro if the resource is 0?  This could be a class ability (class_resource or other_resource) or even any of the repeating resources for ammo, potions, etc?  I see there is a way to prevent healing beyond hp_max so wondering if there is something similar to setting a hard floor of 0 for resources.

To achieve this, I've gone to using the ScriptCards API, that lets you test for a zero value and then conditionally skip.  For example, if a barbarian is out of rages.

Thanks!  Will check it out.  I have it because of the Conjure Animals script that David posted, but haven't messed too much with ScriptCards yet.

Or APILogic can do it right inline with the TM or CSA call.
