JSON is the "Javascript Object Notation", basically a file format for data that's suitable for easy processing by most modern web-based tools.
Several tilde.club servers expose APIs essentially by spitting out JSON as their output, including (list of services here).
If you're looking to parse JSON from the command line with a minimum of code, the `jq` program may be your thing. `jq` is a filter that takes JSON on standard input and produces JSON on standard output. Along the way in the middle you can do various standard sorts of file munging on a field by field basis. [Documentation is in the jq manual.](http://stedolan.github.io/jq/manual/)
