# Get Application Metrics

> Get the metrics of your hosted application.

<ParamField header="Authorization" type="string" placeholder="API Key" required>
  The API key for your account. You can find this in your [account settings](https://squarecloud.app/en/account/security).
</ParamField>

This endpoint returns historical resource usage rather than the current snapshot: up to 288 data points covering the last 24 hours, sampled every 5 minutes, for CPU, RAM, and network. Use it to render a usage chart or to spot trends over time; for the application's current live numbers, use [Get Application Status](/en/api-reference/endpoint/apps/status) or the `status` events on [Real-time Logs](/en/api-reference/endpoint/apps/realtime) instead.

Metrics collection requires at least **512 MB of RAM** allocated to the application; smaller applications return `METRICS_NOT_SUPPORTED`. Results are cached for 2.5 minutes per (owner, application), and the endpoint is rate limited to 10 requests every 5 seconds per user, with a 60-second block once that cap is hit.

### Parameters

<ParamField path="app_id" type="string" placeholder="Application ID" required>
  The ID of the application. You can find this in the URL of your application's dashboard.
</ParamField>

    </ResponseField>

    <ResponseField name="ram" type="number">
