How To Discover

Either:

Implement: https://microformats.org/wiki/representative-h-card-parsing

OR:

Use a microformats2 parser to parse the page / site homepage into JSON
Process that JSON with https://github.com/indieweb/representative-h-card-php which will return a small JSON structure with the representative h-card for the page

Consumers

Telegraph checks the URL of the person who logged in for a representative h-card to show their name and photo when logged in
