Changelog

All notable changes to the Reading List API and its documentation are recorded here. The API follows semantic versioning: a change that could break existing clients increases the major version, a backward-compatible addition increases the minor version, and a fix or clarification increases the patch version.

1.0.0: 2026-10-14

Initial release.

Added

  • GET /books: list books, with optional status and limit query parameters.
  • POST /books: add a book to the reading list.
  • GET /books/{bookId}: get a single book by its ID.
  • API key authentication through the X-API-Key header.
  • Problem Details error responses (RFC 9457) for 400, 401, and 404, with field-level errors on 400.
