    project_id="your_project_id",
    base_url=ApiUrls.mainnet.value
)

Cardano-CLI

from pccontext import CardanoCliChainContext, CardanoCliNetwork
from pathlib import Path

            binary=Path("cardano-cli"),
            socket=Path("node.socket"),
            config_file=Path("config.json"),
            network=CardanoCliNetwork.MAINNET,
)
