I do use it, and it's a nice additional layer in forcing APIs to a) remain consistent and b) increase security. I think the only public program I'm using it in is my dynamic DNS widget: https://github.com/chapmajs/dynamic_dns https://github.com/chapmajs/dynamic_dns My main interest in using JSON Schema in the above project was security related: this service sits on the public Internet, by nature I cannot restrict the sources that connect to it (road warrior type systems couldn't send DNS updates!). Having a strict schema is another layer of sanitization on what one nowadays must assume is a malicious source.
