The iP() function (formerly BV()) now checks the source of authentication more granularly.

envANTHROPIC_API_KEY
API key sent as X-Api-Key header. When set, this key is used instead of your Claude Pro, Max, Team, or Enterprise subscription even if you are logged in. In non-interactive mode (-p), the key is always used when present. In interactive mode, you are prompted to approve the key once before it overrides your subscription. To use your subscription instead, run unset ANTHROPIC_API_KEY
settingapiKeyHelper
Generate the API credential with your own command
