C-h c C-c C-q runs the command org-set-tags-command.
org-set-tags-command calls org-set-tags. Looking through org-set-tags in
org.el, there's a part starting with a comment:

	;; Get a new set of tags from the user
        ...
		  (let ((org-add-colon-after-tag-completion t))
		    (org-trim
		     (org-icompleting-read "Tags: "
					   'org-tags-completion-function
					   nil nil current 'org-tags-history))))))
        ...

So, I guess org-icompleting-read is, what you are looking for.
