As per https://www.google.com/transparencyreport/https/ct/#domain=reddit.com&incl_exp=true&incl_sub=true

This displays a list of subdomains which have unique certificates.

The format of the result is:
https://www.google.com/transparencyreport/jsonp/ct/search?domain=slashdot.org&incl_exp=false&incl_sub=true&c=_callbacks_._4ixq9krnx

The response includes the nextPageToken and prevPageToken entries to paginate.

Then it retrieves information about each of the certificates using calls to:

https://www.google.com/transparencyreport/jsonp/ct/cert?hash=1i%2BzC5oz%2FUiwRYhKSRHK8chUcH3dkMADtdXDF2kbU8o%3D&c=_callbacks_._9ixq9p1iz

This includes DNS names.
