Zhihu Ebook and Chapter Search by Keyword (First 20 Results)

omnial/zhihu-web-fetch-ebook-search

Given a search keyword, returns the first 20 matching items from Zhihu's ebook store, whole books and single chapters alike (20 per call in testing): for each, its title and blurb as plain text (search highlighting removed), the credited author line (for a chapter it names the book the chapter comes from instead), publish time, the card's footer label (a comment or upvote count, often empty), its product and SKU IDs, and its Zhihu page link. Also returns the broad subject category Zhihu assigns to the keyword and a flag saying whether more results exist; no later page is offered.
