# Guide: Usage & Billing

> Monitor your resource consumption and manage your plan.

Karada provides real-time visibility into your project's resource consumption. The **Usage** tab in your Project Dashboard delivers a clear picture of how your deployments and integrations perform.

## Usage Metrics

Karada tracks three key metrics over a rolling **30-day window**:

<CardGroup cols={3}>
  <Card title="Total Invocations" icon="signal">
    The total number of API requests processed by your deployed server or
    application.
  </Card>

  <Card title="Bandwidth" icon="cloud-arrow-down">
    The total data transferred (in bytes) across all requests and responses.
  </Card>

  <Card title="Error Rate" icon="circle-exclamation">
    The percentage of requests that returned an error status code (4xx or 5xx).
    A healthy project should maintain an error rate below 1%.
  </Card>
</CardGroup>

## Understanding the Dashboard

The Usage page also includes additional insights to help you optimize:

### Requests by Region

A geographic breakdown showing where your API requests originate. Use this to understand your user base and optimize deployment regions.

### Top Endpoints

A ranked list of your most-called API endpoints, displaying the request count and relative traffic distribution. Use this to identify hotspots and optimize performance where it matters most.

## Billing Plans

Karada offers flexible pricing tiers based on your usage needs. Billing is managed at the **Workspace** level, meaning all projects within a workspace share the same plan.

## Managing Your Plan

To upgrade, downgrade, or manage your billing:

1. Navigate to **Account Settings** → **Billing**.
2. View your current plan and usage against your limits.
3. Click **Upgrade** to move to a higher tier, or **Manage Subscription** to update payment details.

All plan changes take effect immediately. Upgrades are prorated, and downgrades apply at the end of your current billing cycle.
