Hi Anand,
Under the hood, titles are obtained from the
Pageview API and then supplementary information for our desired titles is obtained from the REST API's
page summary endpoint. That would be the easiest way to go if you'd like to go in a slightly different direction from what's provided in our featured feed endpoint.
If you'd like, you can view the implementation for the "mostread" section of our aggregated feed endpoint here:
Please note that as of now the REST API endpoints are officially designated as unstable.
Best,
Michael
