If for some reason it didn't work, try using it with python:

Usage & Examples

Selecting processing instance

You can set processing instance url, api key and user-agent to enviroment variables, pybalt will use them if none was provided.

COBALT_API_URL=YOUR_INSTANCE_URL
COBALT_API_KEY=YOUR_API_KEY
COBALT_USER_AGENT=YOUR_USER_AGENT

By default pybalt tries to parse any avalible instance for you. I recommend hosting your own instance or asking someone to give you api key for their instance.

As a CLI

Every command here uses the cobalt alias, you can also use pybalt or python -m pybalt as well.

By default all downloads are saved in a user downloads folder ~/Downloads or the one specified by the --folder flag.

Get list of all available commands by running:

cobalt -h
