Search Goodreads for books by title/author/ISBN.

Uses the JSON autocomplete endpoint (no auth, no HTML parsing). Returns book_id, title, author, rating info, and a cover URL.

max_results: how many to return. The autocomplete endpoint itself answers with at most ~5 matches, so a larger value returns what Goodreads sent, not more.

Get full details for a book by its Goodreads id (numeric, or numeric-slug like '11870085-the-fault-in-our-stars').

Parses the page's embedded NEXT_DATA JSON (Apollo state) rather than scraping the DOM, which survives markup changes. Includes the full ratings histogram, all series memberships, and review-language breakdown — use get_reviews for the actual review text. review_language_limit controls how many languages are returned (default 5, maximum 25).

When you cite details or ratings from this book, link to its 'url'.

Get reader reviews for a book — the actual review text, not just a score.

Fetches from Goodreads' GraphQL backend with true pagination, so limit can exceed the ~30 shown on a page. Reviews come in "most relevant" order and aggregate across all editions of the work. Each review has the reviewer name, star rating (1-5), full text, like/comment counts, date, a spoiler flag, a 'url' permalink (use it to cite/link), and the reviewer's profile url.

limit: max reviews to return (capped at 100 to stay polite). min_rating / max_rating: server-side star filters, each 1-5, e.g. min_rating=4 for positive reviews, max_rating=2 for the critical ones. exclude_spoilers: drop reviews flagged as spoilers. Paging is capped, so a book whose reviews are mostly spoilers can return fewer than limit.

'has_more' is true when Goodreads has reviews this call did not read.

"Readers also enjoyed" — books similar to the given one.

Goodreads' own recommendation graph (hard to reproduce with web search). Each result has book_id/title/author/rating/url so you can chain into get_book or get_reviews. Results paginate in batches and limit is capped at 100.

List an author's works (bibliography), given any of their books.

Resolves the book's primary author, then returns their works ranked by popularity. Each result has book_id/title/author/rating/url. Results paginate in batches and limit is capped at 100.

List the books in a series (with reading-order placement), given any book in that series. When a book belongs to multiple series, pass the zero-based series_index from get_book's series_memberships order.

Each entry has the series 'placement' (e.g. '1', '0.5' for a prequel), 'is_primary' (a main-sequence entry vs companion), and the usual book_id/title/author/rating/url. Results paginate in batches and limit is capped at 100.

List published editions of a book (formats, ISBNs, publishers, dates).

Useful for "which edition / format / ISBN" questions. Results paginate in batches and limit is capped at 100.

List the Listopia lists a book appears on (e.g. "Best Dystopian Fiction"), ordered by popularity.

Each list has its title, total member votes, how many books it contains, and a 'url'. Good for "what kind of book is this / what's it grouped with" and for discovery. Results paginate in batches and limit is capped at 100.

Most popular books by release date — Goodreads' "Popular by date" chart.

Ranks the books/works released in a given year (or a specific month of a year) by how many Goodreads members have added them. Mirrors the goodreads.com/book/popular_by_date/[/] page.

year: 4-digit release year. month: optional 1-12 for a single month; omit for the whole year. limit: how many to return (capped at 50).

Each entry has rank, count (members who added it), and the usual book_id/title/author/rating/url so you can chain into get_book/get_reviews.

Compare several books side by side by rating and rating distribution.

Fetches each book and returns them ranked best-to-worst by average rating, with the ratings_histogram plus 'pct_positive' (share of 4-5 star) and 'pct_critical' (share of 1-2 star) so you can judge not just the average but how divisive each book is. Pass 2-10 book ids (from search_books etc.); more than 10 is refused rather than silently trimmed, so split the call.

List books on a shelf via its RSS feed (public shelves; no auth).

Common shelves: 'read', 'currently-reading', 'to-read', plus any custom shelf name. RSS pages hold ~100 items; pass page=2,3,... for more (pages start at 1). Defaults to the configured GOODREADS_USER_ID.

When you cite a book from a shelf, link it to its 'link' field.

List a user's shelf names (scraped from their public profile page; best effort). Defaults to the configured user.

Covers the exclusive shelves (read, to-read, ...) and custom shelves; every name works as get_shelf's 'shelf' argument. Raises LoginRequired for a private profile. The profile page may cap a very long shelf list.
