# Introduction

> Visual Intelligence — stateless REST APIs for video scraping, transcription, video/image understanding, embeddings, and live-stream processing.

Visual Intelligence is a collection of **stateless REST APIs** you call directly on your own video, image, and audio data. No persistent library, no indexing — pick the endpoint that matches your task, send a request, get a result.

If you want a persistent, indexed video + image library you can query by natural language or image, you want the [**Visual Search**](/visual-search/introduction) product instead.

## Hosts

Most endpoints live on `https://mavi-backend.memories.ai/serve/api/v2`. Two specialty hosts are used for specific groups:

| Group                              | Host                                            |
| ---------------------------------- | ----------------------------------------------- |
| Most Visual Intelligence endpoints | `https://mavi-backend.memories.ai/serve/api/v2` |
| Live Video Understanding           | `https://stream.memories.ai`                    |
| Human ReID & Caption (Security)    | `https://security.memories.ai`                  |

Each endpoint page includes a banner with its exact host and the authentication header to use.
