We've always wanted to have an API. "What's an API?" you might ask. Well, an API, or Application Protocol Interface, is a sort of standard that says "If you ask me questions in a particular format, I'll answer them in a particular format."
Our API currently is only for characters, but we will definitely expand it to include Works and Places (as with everything in WhatCharacter, we start with characters, and work our way out).
If you would like to see the API specification, please check out the API page. It requires a user account and and API key. Since registration is currently closed, you can request a user account by filling out the form on the registration page, and once you're in, you can request an API key from your user account page.
In the meantime, if you have any questions, comments, or concerns, please feel free to use the Feedback link at the bottom of the page, or send an email to firstname.lastname@example.org.
