# Introduction

> OpenFiles provides file operations for AI agents through SDKs and REST API. Your agents can create, read, edit, and manage files with automatic versioning.

OpenFiles integrates with your AI application through three approaches:

1. **Direct Integrations** - Drop-in replacement for OpenAI SDK with automatic file operations
2. **Tools** - Provider-specific tool definitions for OpenAI, Anthropic, and other AI providers
3. **Core SDK & REST API** - Direct file operations without AI dependencies

## File Storage

* **Paths**: Specify paths without a leading slash (`docs/readme.md`)
* **Versioning**: Automatic version tracking for all changes
* **Size Limit**: 10MB per file operation

## Authentication

All operations require an API key from [console.openfiles.ai](https://console.openfiles.ai).

```bash theme={null}
# Set environment variable
export OPENFILES_API_KEY="oa_your_key_here"
```
