Architecture Overview

Multilogin X uses a two-tier API architecture:

Component	Base URL	Purpose
Cloud API	`https://api.multilogin.com`	Authentication, profile CRUD, workspace management, 2FA, object storage
Local Launcher	`https://launcher.mlx.yt:45001`	Starting/stopping browsers, script runner, import/export, extensions

All requests use JSON. Most endpoints require a Bearer Token obtained via POST /user/signin.
