Is this the real time Google indexing API? Google is now piloting the search live coverage carousel which is powered by AMP and Atom.
Google published on the developer site information about the search live coverage carousel, which lets publishers feed Google breaking content in real time that is related to live sports, elections and breaking news.
This does seem directly related to the real-time indexing API announcement made at Google I/O in May by Richard Gingras.
This “search live coverage carousel” is a “pilot” that Google is opening up to select publishers. Publishers can apply by filling out this form over here. It allows Google to “surface content more quickly than is currently possible with a standard crawl on your website.” Google said content that makes sense for this live coverage carousel includes “live sports, elections, and breaking news” and “can include live blogs, full length articles, videos and more.”
