Anyone knows of a web service where I could get either the number of chapters or list the chapter names of a book?
I've checked Google Books API and couldn't find this info.
Thank you.
You might want to have a look at the Open Librayr API: https://openlibrary.org/dev/docs/api/books
The jscmd=details query parameter might be of use for you, since it returns a table of contents.
