One setup file: unlimited-cli-setup.bat (Windows), unlimited-cli-setup.command (macOS), or unlimited-cli-setup.sh (Linux). It downloads the CLI package and installs dependencies.

Where do I get the API key?

From the post-payment delivery email/Telegram or Dashboard → API access. It is a virtual Unlimited API key, not a third-party chat site token.

What if Windows blocks the .bat?

SmartScreen may warn on unsigned scripts. Use More info → Run anyway only if the file came from unlimitedcodex.com/downloads/.

No for Unlimited Luna CLI. Codex has a separate setup guide if you use that client.

Unlimited Luna CLI · Setup

Install in 3 simple steps

Get your key → download the setup file for your computer → paste the key and start chatting.

No ChatGPT login neededKey from dashboard or email only

1 · Get your key
2 · Download setup
3 · Run & chat

Step 1

Where is my API key?

New accounts: open Dashboard and click “Start 10-minute test”. Paid accounts: the key is emailed right after payment.

Dashboard (recommended)

We also send the key by email. Check inbox and spam. Base URL is always api.unlimitedcodex.com.

Never share the full key. Support only needs the short prefix and the error text.

Open dashboard

Step 2

Pick your computer

Choose Windows, macOS, or Linux, then download the matching setup file.

Easiest path

One setup file does the work

The setup file installs Unlimited Luna CLI, asks for your key, saves login, and opens chat.

11. Download the Windows setup file (button below).
22. Double-click the file. If Windows warns you: More info → Run anyway.
33. Wait for install (needs internet + Python 3.9+).
44. When asked, paste your API key from the dashboard or email.
55. Chat starts. Next time just type: unlimited

Download Windows setup Optional: Windows .exe Text guide

You need Python 3.9+ first. Install Python On Windows, enable “Add python.exe to PATH”. Offline: put unlimited-cli-package.zip next to the setup file.

Step 3

Daily use after install

You paste the key only once. Later, open chat with one command.

unlimited              # start chat
unlimited status       # show masked key + URL
unlimited update       # install the newest CLI
unlimited doctor       # check install + network
unlimited logout       # remove saved key
unlimited demo         # UI preview without a real key

It worked if…

You see streaming answers in the terminal. unlimited status shows a masked key.

HTTP 401 error

Key is wrong, expired, or ended. Get a new key from the dashboard, then run unlimited login again.

Optional

Manual install (advanced)

Only if you prefer pip yourself. Most people can skip this.

unlimited-cli-package.zip unlimited-cli.exe unlimited-cli-setup.sh

# zip package (any OS):
pip install -r requirements.txt
pip install .
unlimited login --key sk-...
unlimited

# Windows exe:
unlimited-cli.exe login --key sk-...
unlimited-cli.exe

# Linux:
chmod +x unlimited-cli-setup.sh && ./unlimited-cli-setup.sh

# macOS:
chmod +x unlimited-cli-setup.command && ./unlimited-cli-setup.command

# offline:
# put unlimited-cli-package.zip next to the setup file, then run it

FAQ

What do I download?: One setup file for your OS: .bat on Windows, .command on macOS, .sh on Linux. It installs the CLI for you.
Do I need Codex or another IDE?: No. Unlimited Luna CLI works in the terminal by itself. Codex IDE is a different product path.
Windows shows a warning?: That can happen with unsigned scripts. Use More info → Run anyway only if you downloaded from unlimitedcodex.com.
Where do I start the free test?: Create an account, open Dashboard, click “Start 10-minute test”. One free test per account.
