HeyGen's self-serve (Pay-As-You-Go) plan lets you purchase USD balance when you need it — no monthly subscription, no commitments.

## How Billing Works

When you authenticate with an **API Key** (`x-api-key` header), you are billed under the **API tier**. Usage is deducted from your prepaid USD wallet.

Check your balance at any time:

```text theme={null}
GET /v3/users/me → wallet
```

<Callout icon="⚠️">
  **OAuth vs API Key:** If you authenticate with an OAuth bearer token, usage is billed against your **web plan**, not the API tier. Check your web plan balance with `GET /v3/users/me → subscription`.

  Using an **API Key** is recommended for automation and integration workflows. API key authentication provides higher concurrency limits and is more flexible and powerful for programmatic use.
