Firm API keys

A firm can give its people Studio's agent without each one having a Claude account. The firm gets one budget with a monthly spend limit, and each person gets their own key under it, so one key can be revoked alone. Studio hands the key to Claude Code, so you do not sign in to Claude. Claude Code must still be installed (see Set up the agent).

Use a key you were given

1. Open Settings… (⌘, or ?) and find AI.
2. Paste the key (it starts sk-ant-) into Anthropic API key.
3. Click Save key. Settings now says Using firm key.

Where the key is kept

The key is kept in the system's secure store: the Keychain on macOS, the Credential Manager on Windows, the Secret Service (GNOME Keyring or KWallet) on Linux. It is never written to a project folder or a conversation.

Note. On Linux with no Secret Service running, Studio starts without a key and saving one says so. Start GNOME Keyring or KWallet and log in again, or set ANTHROPIC_API_KEY before you start Studio.

Stop using the key

Click Remove key. Studio deletes it and goes back to your own Claude sign-in (Using your Claude sign-in).

When the key stops working

When the firm's monthly limit is reached, or the key is revoked, the next agent turn fails and the chat says "Your firm's AI budget is used up or the key was revoked. Contact Urbium." Ask for a new key and paste it over the old one.

For the firm

• Each person's key is separate: revoke one and the others keep working.
• The spend limit bounds what any key, even a copied one, can cost in a month.
• Each conversation shows its tokens and cost, so people can see what their work costs. See Agents and chat.
