How to get Activity URL from Target API

Use case :

We have a requirement according to which we need to notify authors in case they are trying to edit a page that has a target activity associated with it.

Solutions we tried:

We tried to explore Target API's for the same using https://developers.adobetarget.com/api/#activities

Surprisingly, when we fetch activities details from the API, everything except activity URL comes back from the API.

API's we have tried 

List activities - https://mc.adobe.io/racv/target/activities
Get AB Activity by ID - https://mc.adobe.io/racv/target/activities/ab/<<activity id>>
Get XT Activity by ID - https://mc.adobe.io/racv/target/activities/xt/<<activity id>>

Questions

1. Is there any way to fetech activity URL from Taregt API's ? It's visible on the target interface surely there is something which we are missing.

2. Is there any solution that can solve this use case?
