API

WolneLektury.pl API resides under https://wolnelektury.pl/api/. You can use it to access information about books, their fragments and their metadata.

Default data serialization format is JSON, but you can also use XML by appending ?format=xml query parameter to each URL.

The URLs in WolneLektury.pl API are:

/api/books/ – All books
/api/audiobooks/ – Audiobooks
/api/daisy/ – DAISY
/api/authors/ – List of all authors
/api/epochs/ – List of all epochs
/api/genres/ – List of all genres
/api/kinds/ – List of all kinds
/api/themes/ – List of all themes
/api/collections/ – Collections

Each element of those lists contains a link (in a "href") attibute which points to individual resource's details, i.e.: /api/books/studnia-i-wahadlo/ or /api/authors/edgar-allan-poe/.

You can combine authors, epochs, genres and kinds to find only books matching those criteria. For instance: /api/authors/adam-mickiewicz/kinds/liryka/books/.

If you only want top-level books and not all the children, you can use /parent_books/, as in: /api/authors/adam-mickiewicz/kinds/liryka/parent_books/.

The same way, using also books and themes, you can search for a list of fragments: /api/authors/william-shakespeare/themes/zabawa/fragments/. Again, each entry has a "href" attribute which links to the fragment's details, i.e.: .
