# System API

This API provides various system functionalities, including stream and VOD management, system statistics, directory browsing, log viewing, process management, EPG/nginx reloading, and more.

---

## File Location

The System API is handled by the controller:

```text
src/public/Controllers/Api/InternalApiController.php
```

HTTP entry-point: `/api.php` -> routed by nginx to `public/index.php` with `XC_API=internal`.

## API Architecture Overview

**Base URI:** `http://<host>:<http port>/api.php`
**Authentication:** `password` parameter matching the `live_streaming_pass` configuration
**Example:**
`http://<host>:<http port>/api.php?password=<live_streaming_pass>&action=<api endpoint>`
