## About

## What it does

Book Search API provides access to a catalog of books and authors. It allows you to search for authors, search and filter books, retrieve detailed information for a specific book, and find books similar to a given title.

Use it when you need book catalog data for reading applications, book discovery and search, recommendation features, library tools, catalog enrichment, or internal knowledge systems.

Search Authors lets you find authors by name with optional pagination using `number` and `offset`. Search Books supports free-text search and filtering by ISBN, OCLC number, author, genre, rating, publication year, result grouping, sorting, and pagination.

Get Book Information retrieves detailed information for a specific book, including its title, subtitle, cover image, external identifiers, authors, publication details, description, and rating. Find Similar Books returns a list of books related to a specified book, with an optional `number` parameter to control the number of results.

The API returns structured JSON responses that can be used directly in search interfaces, book discovery workflows, recommendation systems, and catalog enrichment pipelines.
