“JSONRPCake is a command line JSON-RPC client that wraps the jsonrpc-ns library. It is a fork of HTTPie written by Jakub Roztocil. Its goal is to make CLI interaction with JSON-RPC 2.0 services as human-friendly as possible. It provides a simple jsonrpc command that allows for sending arbitrary JSON-RPC requests using a simple and natural syntax, and displays colorized responses. JSONRPCake can be used for testing, debugging, and generally interacting with JSON-RPC servers.
JSONRPCake is written in Python, and under the hood it uses the jsonrpc-ns and Pygments libraries.”
