Getting started with XPNCORE takes just 4 steps: create an API key, top up your wallet, choose how to pay, then connect your tool.
Step 1: Create an API key
- Open API keys in the sidebar.
- Click Create key, name it after where you will use it (for example Laptop – Claude Code), then click Create key.
- Copy the key and keep it somewhere safe.
Never share your API key. If a key leaks, revoke it and create a new one right away.
Step 2: Top up your wallet
- Open Wallet & top-up (or click Top up at the top of the page).
- Pick an amount, then scan the VietQR code with any banking app.
- Use your transfer code as the whole transfer note (the QR code fills it in for you). The money reaches your wallet within a few minutes.

Step 3: Choose how to pay
| Option | Best when | How |
|---|---|---|
| Buy a plan | You use it often and want a fixed monthly cost. | Go to Plans, pick a plan and pay with your wallet balance. |
| Pay per model | You use it lightly or irregularly and only want to pay for what you use. | Nothing else to do: each request is charged to your wallet at the model's price. See prices on Models & Pricing. |
One API key works for both. With a plan, models included in it count against the plan; everything else is charged to your wallet.
Step 4: Connect your tool
- Open Connect in the sidebar.
- Select the API key you just created — it is filled into the command for you.
- Choose your tool (Claude Code, Codex, Cursor, Cline…) and the model you want.
- Copy the single command shown, paste it into Terminal (macOS/Linux) or PowerShell (Windows) and run it.
