Maybe a bit off-topic, but the Grand Comics Database (http://www.comics.org) is an fan non-profit effort to index all comic books worldwide. We don't have an API, although we'd like to - it's mostly that we have no clear requirements yet, and since all data is available as a DB dump under CC-BY, there's not much push for one.
The project is now in its 20th year and this shows in that the database schema isn't as canonicalized as could be (for example, creator credits and character fields are just text fields and not DB references. Yet slowly but surely improvements are being made, faster in the last couple of years.
We could use some help if anybody is interested - our code is GPL (https://github.com/GrandComicsDatabase/gcd-django) and since the dev team is limited and everything happens on our free time, all kinds of help are appreciated.
