Comet Hub - API Documentation

Getting Started

The Comet Hub API allows you to programmatically generate alt accounts, check Roblox cookies, and fetch user information. This documentation will guide you through making your first API request.

Base URL

All API requests should be sent to:

https://api.comethub.net

Available Actions

The API supports multiple actions, specified via the action header:

genalt Generate a new Roblox alt account (counts towards daily limit)

check-cookie Validate a Roblox cookie (does NOT count towards daily limit)

user-info Get detailed Roblox user information (does NOT count towards daily limit)

Authentication

API requests require authentication using a developer token provided in the request headers.

⚠️ Important

To get a developer token, please contact us in our Discord server by making a ticket. Developer tokens are only provided to approved users. (Certain use cases are paid, or require you to have a lifetime Comet Hub key)
