VNAI Pro

Getting started

Three steps — create an API key, install Node.js, pick your tool

Create an API key first

Follow the API key guide, then check all three requirements:

  1. Sufficient balance: https://api.vnaipro.app/wallet.
  2. Available key quota: https://api.vnaipro.app/keys.
  3. Correct group: choose Auto to use one key for Codex, Claude, and other supported models. Dedicated groups only allow models within that group.

Create your key at https://api.vnaipro.app/keys. With the Auto group, paste the same key into your Codex and Claude configurations.

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
