Get all lists on subsites by content type with REST API

Question

I want to get all lists from subsites etc. based on their content type with REST Api. For particular list ("ProjectList") this works:

 /_api/Web/lists/GetByTitle('ProjectList')/Items? 
 $select=ContentType/Name&$expand=ContentType&$filter=ContentType eq 
 'Message'`

But how will I be able to retrieve ALL lists, including subpages etc. by their content type?

I have tried:

  /_api/Web/lists/Items? 
   $select=ContentType/Name&$expand=ContentType&$filter=ContentType eq 
   'Message'`

Without luck.

You want to get the all Items with content Type "Message" from Root site and sub sites or you want to get all the lists where this content Type attached. if it is First then you should use Search Rest API to get the All items from Web with Content Type="Message" sharepoint.stackexchange.com/questions/234200/… — vinit kumar, Commented Oct 12, 2018 at 12:33

If you want to get list then you don't have to append "items" to your rest url:

/_api/Web/lists?$select=ContentType/Name&$expand=ContentType&$filter=ContentType eq 'Message'
