CLI

Each command, the subcommands and flags its branch of run reads, whether it needs a Phantom AI key, and the Phantom AI calls it can make (see HTTP calls). Every command also takes the flags in the Flags section of the help text.

HTTP calls to Phantom AI

Every call goes to PHANTOM_BASE_URL (default DEFAULT_BASE_URL, https://phantom.codes/v1), which must be https ( httpsOnly). A failed call becomes a PhantomApiError. <apiKey> is the key the command runs as, except DELETE /key, which sends the key being deleted.

Environment variables

Secret: holds a secret, so keep it out of files, logs and the model's context. Environment only: no flag or tool argument can set it. Cap: limits what an agent can spend or send. The list is ENV_VARS.

Variable	Meaning	Secret	Environment only	Cap
PHANTOM_API_KEY	your Phantom AI API key (or save one with login)	yes
PHANTOM_KEY_NAME	run as a key saved with key save or child --save; wins over PHANTOM_API_KEY
PHANTOM_BASE_URL	API base, https:// only (default https://phantom.codes/v1)
PHANTOM_STATE_DIR	where pai keeps keys, wallets, notes and mail settings (default ~/.config/phantom-key)
PAI_KEYCHAIN	0 saves keys, wallets and the mail login to files instead of the macOS Keychain; 1 uses the Keychain on any system, which fails where /usr/bin/security is missing
PAI_MEMORY_SPACE	which space memory and browser use (default: the key name, or main)
PAI_SANDBOX_ENGINE	docker or podman (default: whichever is running)
PAI_MAIL_PASSWORD	the mail password for mail setup, instead of the prompt	yes
PAI_MAIL_SEND	1 lets pai send mail; otherwise it only drafts		yes
PAI_MAIL_MAX_PER_DAY	most recipients pai may send to in 24 hours, default 10		yes	yes
PAI_MAIL_SEND_TO	comma-separated addresses or @domains pai may send to (default: anyone)		yes
AGENT_BROWSER_PROFILE	Chrome profile folder, or a profile name such as Default (default: one per space)
AGENT_BROWSER_SESSION	agent-browser session name (default pai-<space>)
PHANTOM_WALLET_MAX_USD	most one wallet payment may spend; required to pay		yes	yes
PHANTOM_WALLET_MAX_USD_PER_DAY	most the wallet may spend in 24 hours (default: PHANTOM_WALLET_MAX_USD)		yes	yes
PHANTOM_WALLET	name of the saved wallet that pays, instead of the default
PHANTOM_WALLET_KEY	secret key (base58 or JSON array), instead of a saved wallet	yes
PHANTOM_WALLET_FILE	a keypair file, instead of a saved wallet
PHANTOM_SOLANA_NETWORK	mainnet (default) or devnet
PHANTOM_SOLANA_RPC	Solana RPC URL (default: Solana's public RPC for the network)

pai also reads these, which are not its own settings:

Variable	Why pai reads it
HOME	Home folder. setup looks here for agents to set up and for ~/.claude/settings.json (default: the system home folder)
ANTHROPIC_API_KEY	setup --agent claude --provider warns when it is set, because Claude Code would send it instead of the Phantom AI key
ANTHROPIC_AUTH_TOKEN	setup --agent claude --provider warns when it is set, for the same reason

pai sets these for other programs:

Variable	Where
AGENT_BROWSER_SESSION	Set for agent-browser by browser: pai-<space> unless already set
AGENT_BROWSER_PROFILE	Set for agent-browser by browser: <state>/browser/<space> unless already set
ANTHROPIC_BASE_URL	Written to the env block of ~/.claude/settings.json by setup --agent claude --provider; removed by --provider off
ENABLE_TOOL_SEARCH	Written as true to the same env block, for the same command
ANTHROPIC_MODEL	Written to the same env block when --model is given
