pilad

pilad is the daemon that runs the piladb server, manages the main pila, databases and stacks. It exposes a RESTful HTTP server that listens to requests in order to interact with the engine.

Note: pilad API does not come with a built-in pretty option. We encourage to use jq to visualize JSON data on the terminal, or advanced CLI HTTP clients like HTTPie.
