does PI WebAPI provide a method for finding elements by an Extended Property as PI AF SDK does?
It does not appear that the PI Web API supports this kind of search. It does not appear that the new AFElementSearch options support this kind of search either so it looks like if you want to do this, this method is your only option. How are you using the Extended Properties of an AF Element that you want to filter on this field?
I'm storing some specific data in extended properties I don't want to show up in the elements attributes. That is why I try filtering on these items. I'm currently developing a small web application where I'd rather use PI WebAPI than my own web service that uses the AF SDK.
There are plans to add an ExtendedProperty filter to the new query searches like AFElementSearch in the AF SDK, but it has not been implemented yet.
