## Credit System

Winnie uses a credit system to charge for API usage. Different request types consume different amounts of credits:

| Request Type         | Credit Cost     |
| -------------------- | --------------- |
| Standard RPC         | 1 credit        |
| Enhanced RPC         | 2 credits       |
| WebSocket Connection | 10 credits/hour |
| Webhook Delivery     | 5 credits       |
| Archive Data         | 10 credits      |

You can check your current credit usage in the dashboard:

```typescript theme={null}
// Check current subscription credits programmatically
const credits = await client.subscription.getCredits();
console.log(`Remaining credits: ${credits.remaining}`);
```

## Billing Cycles

Subscriptions are billed monthly or annually (with a discount). The billing cycle starts on the day you subscribe.

<Tip>
  Annual subscriptions typically come with a 10% discount compared to monthly billing.

## Auto-scaling

For paid plans, Winnie offers auto-scaling to handle traffic spikes:

    Configure auto-scaling in your dashboard settings
  </Step>

  <Step title="Define Limits">
    Set a maximum credit limit for auto-scaling
  </Step>

  <Step title="Monitor Usage">
    Track auto-scaling usage in real-time
  </Step>
</Steps>

<Note>
  Auto-scaling usage is billed at the end of your billing cycle at a 20% premium over your standard rate.
</Note>

## Upgrading and Downgrading

You can change your plan at any time through the dashboard:

* **Upgrades** take effect immediately

* **Pro-rated billing** applies when upgrading mid-cycle

Enterprise plans offer additional features:

* **Custom infrastructure** tailored to your needs
