# Overview

> Use the AirCloud External API to programmatically manage your endpoints.

The AirCloud External API provides programmatic access to your container endpoints. Integrate GPU infrastructure into your applications, workflows, and automation systems.

## Available resources

* **Endpoints**: Start, stop, scale, and monitor container endpoints.
* **Replicas**: View live replica status for active endpoints.
* **Logs**: Access endpoint log files and their contents.

## Authentication

All requests require an [API key](/docs/quickstart) in the request headers. Pass your API key as a Bearer token in the `Authorization` header.

```bash theme={null}
Authorization: Bearer YOUR_API_KEY
```

<Note>
  API Keys can only access the projects and endpoints specified at creation time.
</Note>

## Important notes

* Replica scaling is only available when the endpoint is **active**.
* Endpoints with autoscaling enabled cannot be manually scaled.
* Endpoint settings can only be patched (PATCH) when the endpoint is **inactive**.
