VNAI Pro

Getting started

Three steps — buy a key, install Node.js, pick your tool

Buy an API key

Contact us to get an API key (formatted sk-...):

Each key works with its matching product (Codex or Claude Code).

Install Node.js (if you haven't)

Both Codex and Claude Code install via npm, so you need Node.js 18 or newer. Check with:

Terminal
node --version

If missing, install it for your OS:

Terminal
brew install node

Or download the installer from nodejs.org.

Run the install command

Open the install page for your tool, paste your key, copy the command and run it:

Install Codex

CLI + VS Code extension + app — one setup covers all three

Install Claude Code

Claude Code CLI with the full Claude lineup
