The HiFi Query language is a simple, JSON-based language for pulling data from your website. While simple, it is extremely powerful. The entire HiFi application was built on top of the API, which means it should have no problem handling most websites.

That is a quick overview of how the language works. This simple concept can be extended to do all kinds of powerful things. For details on the ideas, look at all of the documentation in this section.
