Why it exists

Open Library trend data, without the plumbing

Book attention moves differently from social buzz: a title climbing the Open Library trending feed is holding readers, not just catching a spike. For publishers, booksellers, authors and media, that is a signal worth tracking alongside search and social.

Open Library exposes a trending view but not a clean programmatic feed for it. Trends API serves the daily trending-books feed as JSON in the same shape as the other 20 live feeds, so you can line reading attention up against search, social and shopping signals.
