Base URLs & Architecture

Multilogin X exposes two separate API surfaces. Understanding which to use for each operation is critical.

Cloud API

Base URL: https://api.multilogin.com

Used for all server-side operations that do not require the local agent:

Category	Example Endpoints
Authentication	`/user/signin`, `/user/refresh_token`
Profile Management	`/profile/create`, `/profile/update`, `/profile/remove`
Workspace	`/workspace/profiles`, `/workspace/folders`
2FA	`/user/setup_2fa`, `/user/disable_2fa`
Object Storage (metadata)	`/api/v1/resources/metas`, `/api/v1/resources/types`

Base URL: https://launcher.mlx.yt:45001

Used for operations that require the local Multilogin X Agent to be running:

Category	Example Endpoints
Start/Stop Profiles	`/api/v1/profile/f/:folder_id/p/:profile_id/start`
Script Runner	`/api/v1/run_script`, `/api/v1/scripts`
Import/Export	`/api/v1/profile/:profile_id/export`, `/api/v1/profile/import`
Extensions	`/api/v1/create_extension_from_url`
Object Storage (files)	`/api/v1/object_storage/upload`, `/api/v1/object_storage/create_and_upload`

WARNING

The local launcher requires the Multilogin X Agent to be installed and running. If the agent is not running, launcher endpoints will not respond.

A separate subdomain handles pre-made cookie operations:
