title: Wagtail getting all tags of a specific page type using api
body: <p>I am trying to find a way to get the tag list of specific page types using <strong>wagtail api</strong>.</p>
  
  <pre><code> class BlogPage(FreeFormPage):
          #...
          tags = ClusterTaggableManager(through=BlogPageTag, blank=True)
   class WorkPage(FreeFormPage):
          #...
          tags = ClusterTaggableManager(through=WorkPageTag, blank=True)
  </code></pre>
  
  <p>On the docs it is clear that there are endpoints for pages, documents and images. But I could not find an information on tags.</p>
  
  <ol>
  <li>Do I have to create another specific page type model that collects all the tags and send them via pages endpoint?</li>
  <li>Or do I have to add a custom endpoint for tag model?</li>
  </ol>
