Integration Options

​
OpenAI Integration

When to use: You’re already using the OpenAI SDK 
import OpenAI from '@openfiles-ai/sdk/openai'  // Change this line

const ai = new OpenAI({
  apiKey: 'sk-...',
  openFilesApiKey: 'oa-...'  // Add this line
})
// Everything else stays the same
  • ✅ Minimal code changes
  • ✅ Automatic file operations
  • ✅ Works with existing OpenAI code
  • ❌ Currently limited to OpenAI models

​
Tools

When to use: You’re using Anthropic Claude, multiple AI providers, or need framework flexibility 
import { OpenFilesTools } from '@openfiles-ai/sdk/tools'
import Anthropic from '@anthropic-ai/sdk'

const tools = new OpenFilesTools({ apiKey: 'oa-...' })
const anthropic = new Anthropic({ apiKey: 'ant-...' })

// Use with Anthropic Claude
const response = await anthropic.messages.create({
  model: 'claude-sonnet-4-20250514',
  messages: [...],
  tools: tools.anthropic.definitions
})

// Process file operations
const processed = await tools.anthropic.processToolCalls(response)
  • ✅ Works with OpenAI, Anthropic, and more
  • ✅ Provider-specific optimizations
  • ✅ Mix with your custom tools
  • ❌ Requires manual tool handling

​
Core SDK & REST API

When to use: You need direct control or don’t use AI frameworks 
import { OpenFilesClient } from '@openfiles-ai/sdk/core'

const client = new OpenFilesClient({ apiKey: 'oa-...' })

// Direct file operations
await client.writeFile({ path: 'report.md', content: 'Hello' })
const content = await client.readFile({ path: 'report.md' })
  • ✅ No AI framework required
  • ✅ Full control over operations
  • ✅ Can integrate anywhere
  • ❌ No automatic AI integration
REST API Example: 
# Create a file
curl -X POST https://api.openfiles.ai/functions/v1/api/files \
  -H "x-api-key: oa_your_key" \
  -H "Content-Type: application/json" \
  -d '{"path": "report.md", "content": "Hello World"}'

# Read a file
curl https://api.openfiles.ai/functions/v1/api/files/report.md \
  -H "x-api-key: oa_your_key"
