HTTPie

HTTPie (pronounced aitch-tee-tee-pie) is a command line HTTP
client. Its goal is to make CLI interaction with web services as
human-friendly as possible. It provides a simple http command that
allows for sending arbitrary HTTP requests using a simple and
natural syntax, and displays colorized output. HTTPie can be used
for testing, debugging, and generally interacting with HTTP servers.

This version of httpie includes unix socket support, and in
particular support for snapd:// URLs for ease of interaction with
the snapd REST API.
