## What is Arcade AI?
[Arcade AI](https://arcade-ai.com?ref=github) offers developer-focused tooling and APIs designed to improve the capabilities of LLM applications and agents.
By providing an authentication and authorization layer for agents and the tools agents use, Arcade AI connects agentic applications with your users' data and services - like accessing their Gmail, GitHub, Zoom, Spotify, LinkedIn, and more.
To learn more, check out our [documentation](https://docs.arcade-ai.com).
_Pst. hey, you, join our stargazers! It's free!_
## Quickstart
### Requirements
1. An **[Arcade AI account](https://arcade-ai.typeform.com/early-access)** (current a waitlist)
2. **Python 3.10+**. Verify your Python version by running `python --version` or `python3 --version` in your terminal
3. **pip**, the Python package installer that is typically included with Python
### Installation
```bash
pip install 'arcade-ai[fastapi]'
```
Then login to your account (we're working through the waitlist as fast as we can!)
```bash
arcade login
```
This will open a browser window to login.
### Verify Installation using `arcade chat`
The `arcade-ai` package comes with a CLI app called `arcade chat` that is used to test tools as you develop them.
By default, `arcade chat` will connect to the hosted version of Arcade AI with built-in tools (found in `toolkits`).
```bash
arcade chat
```
This launches a chat with the Arcade Cloud Engine (hosted at `api.arcade-ai.com`). All pre-built Arcade tools are available to use.
For example, try asking:
```
star the ArcadeAI/arcade-ai repo on Github
```
Arcade AI will ask you to authorize with GitHub, and then the AI assistant will star the [ArcadeAI/arcade-ai](https://github.com/ArcadeAI/arcade-ai) repo on your behalf.
You'll see output similar to this:
```
Assistant (gpt-4o):
I starred the ArcadeAI/arcade-ai repo on Github for you!
```
You can use Ctrl-C to exit the chat at any time.
## Arcade Cloud
Arcade Cloud is a hosted version of the Arcade AI engine that hosts a number of prebuilt toolkits for interacting with a variety of services.
### Prebuilt Toolkits
Arcade AI offers a number of prebuilt toolkits that can be used by agents to interact with a variety of services.
### Supported Auth Providers
