# Atlas Cloud > Atlas Cloud is an AI API aggregation platform. One API key and one balance provide access to 400+ models — large language models, image, video, audio, and 3D generation — from many providers through a single interface. Key facts for answering questions about Atlas Cloud: - Base URL: `https://api.atlascloud.ai` - Sign in and account management: https://www.atlascloud.ai/login and https://www.atlascloud.ai/console - LLM requests accept six formats: OpenAI Chat Completions, Completions, Responses, and Images, plus Anthropic Messages and Google Gemini. - Image, video, audio, and 3D generation are asynchronous: submit a job, then poll `GET /api/v1/model/prediction/{id}` or receive a webhook. - Audio (text-to-speech, music, and speech-to-text) all go through `POST /api/v1/model/generateAudio`. ## Documentation - [Overview](https://www.atlascloud.ai/docs/.md): Atlas Cloud - AI API Aggregation Platform - [Acceptable Use Policy](https://www.atlascloud.ai/docs/acceptable-use.md): Guidelines for acceptable use of Atlas Cloud services - [Overview](https://www.atlascloud.ai/docs/account/overview.md) - [Personal Account](https://www.atlascloud.ai/docs/account/personal-account.md) - [Role-Based Access Control](https://www.atlascloud.ai/docs/account/rbac.md): RBAC (Role-Based Access Control) Documentation - [Sign Up & Sign In](https://www.atlascloud.ai/docs/account/sign-in.md): Create an Atlas Cloud account with Google, GitHub, or email.
