Install Codex Desktop and Connect It to TeamoRouter
Codex Desktop is OpenAI's desktop AI coding assistant. Follow the steps below to install it and connect it to TeamoRouter.
New accounts start with a $0 balance — top up before your first request. Top up from $5. If a request returns 402 with "wallet balance is insufficient", your balance is empty — your base URL and key are fine. Top up and retry.
No international card? Top up with USDT: click Pay with crypto in the top-up dialog and pay with USDT, USDC or ETH from Binance, OKX or any exchange app — the checkout shows which networks your amount supports (BEP20 works from $5). No wallet extension needed (guide).

Set the API key
Replace <your-TeamoRouter-key> with your own API key. You can create it in the TeamoRouter dashboard.
macOS
echo 'export OPENAI_API_KEY="<your-TeamoRouter-key>"' >> ~/.zshrc
source ~/.zshrc
Linux
echo 'export OPENAI_API_KEY="<your-TeamoRouter-key>"' >> ~/.bashrc
source ~/.bashrc
Windows
[Environment]::SetEnvironmentVariable("OPENAI_API_KEY", "<your-TeamoRouter-key>", "User")
Windows users: after running the command above, fully close Codex Desktop and open it again so it can read the new environment variable.
Launch Codex Desktop
Open Codex Desktop. If it was already running, quit it completely and reopen it.
You can review usage for each request in the TeamoRouter dashboard.
