# 🤖 Claude API Setup Guide
This guide will help you set up the Claude API for AeThex Studio's **cross-platform code translation** feature - the core competitive differentiator that enables translating code between Roblox, UEFN, Spatial, and Core.
---
## 🎯 Why You Need This
Without a Claude API key:
- ✅ All features work (platform switching, templates, editor)
- ❌ Translation shows **mock responses** (not real AI translation)
With a Claude API key:
- ✅ **Real AI-powered translation** Roblox ↔ UEFN ↔ Spatial ↔ Core
- ✅ Intelligent code conversion with explanations
- ✅ Platform-specific best practices applied
- ✅ Your #1 competitive advantage unlocked 🔥
---
## 📋 Prerequisites
- An Anthropic account
- Credit card for API billing (Claude API is pay-as-you-go)
- Estimated cost: **$0.001 - $0.01 per translation** (very affordable)
---
## 🔧 Step-by-Step Setup
### Step 1: Get Your Claude API Key
1. **Visit Anthropic Console**: https://console.anthropic.com/
2. **Create Account** (if you don't have one)
3. **Navigate to API Keys**: https://console.anthropic.com/settings/keys
4. **Click "Create Key"**
5. **Copy your API key** (starts with `sk-ant-api03-...`)
⚠️ **Important**: Save this key securely! You won't be able to see it again.
### Step 2: Configure Environment Variables
#### Option A: Local Development (.env.local)
1. Create a file named `.env.local` in the project root:
```bash
# From project root
touch .env.local
```
2. Add your API key:
```bash
# .env.local
VITE_CLAUDE_API_KEY=sk-ant-api03-your-actual-key-here
```
3. Restart your dev server:
```bash
npm run dev
```
#### Option B: Production Deployment (Vercel/Netlify)
**For Vercel:**
1. Go to your project settings
2. Navigate to "Environment Variables"
3. Add:
- Key: `VITE_CLAUDE_API_KEY`
- Value: `sk-ant-api03-your-actual-key-here`
4. Redeploy your app
**For Netlify:**
1. Site Settings → Environment Variables
2. Add:
- Key: `VITE_CLAUDE_API_KEY`
- Value: `sk-ant-api03-your-actual-key-here`
3. Trigger new deploy
---
## ✅ Verify Setup
### Test the Translation Feature
1. **Open AeThex Studio** in your browser
2. **Switch Platform** to Roblox (if not already)
3. **Select a Template** (e.g., "Hello World")
4. **Click "Translate" button** in toolbar
5. **Choose Target Platform** (e.g., UEFN)
6. **Click "Translate"**
**If configured correctly:**
- Loading spinner shows
- Real Verse code appears on the right side
- Explanation section shows key differences
- Warnings section (if applicable)
**If NOT configured:**
- Mock translation appears with comment: `-- TODO: Replace with actual uefn implementation`
- Warning: "Mock translation active - integrate Claude API for production"
---
## 💰 Cost Estimation
**Claude 3.5 Sonnet Pricing** (as of Jan 2025):
- **Input**: $3 per million tokens
- **Output**: $15 per million tokens
**Typical Translation Costs:**
- Small script (50 lines): ~$0.001
- Medium script (200 lines): ~$0.005
- Large script (500 lines): ~$0.015
**Example monthly usage:**
- 100 translations/day = ~$0.50/day = **~$15/month**
- 500 translations/day = ~$2.50/day = **~$75/month**
💡 **Tip**: Start with a $10 credit to test. Monitor usage in Anthropic Console.
---
## 🔒 Security Best Practices
### ✅ DO:
- ✅ Store API keys in `.env.local` (never in code)
- ✅ Add `.env.local` to `.gitignore`
- ✅ Use environment variables in production
- ✅ Rotate keys periodically
- ✅ Set spending limits in Anthropic Console
### ❌ DON'T:
- ❌ Commit API keys to Git
- ❌ Share keys publicly
- ❌ Hardcode keys in source code
- ❌ Use same key for dev and prod
---
## 🐛 Troubleshooting
### Issue: "API key not configured" warning
**Solution**:
- Verify `.env.local` exists and has correct key
- Restart dev server (`npm run dev`)
- Check console for errors
### Issue: "API request failed: 401"
**Solution**:
- Your API key is invalid or expired
- Generate new key in Anthropic Console
- Update `.env.local`
### Issue: "API request failed: 429"
**Solution**:
- Rate limit exceeded
- Check usage in Anthropic Console
- Add billing method if needed
- Implement client-side rate limiting (future enhancement)
### Issue: "API request failed: 400"
**Solution**:
- Invalid request format (shouldn't happen)
- Check browser console for details
- Report bug on GitHub
### Issue: Translation returns mock data despite having API key
**Solution**:
1. Open browser console (F12)
2. Look for: "Claude API key not configured, using mock translation"
3. Check environment variable name: Must be `VITE_CLAUDE_API_KEY`
4. Restart dev server after adding key
---
## 🧪 Advanced Configuration
### Custom Model Selection
Use a different Claude model (optional):
```bash
# .env.local
VITE_CLAUDE_API_KEY=sk-ant-api03-...
VITE_CLAUDE_MODEL=claude-3-opus-20240229
```
Available models:
- `claude-3-5-sonnet-20241022` (default, recommended)
- `claude-3-opus-20240229` (most capable, slower, expensive)
- `claude-3-haiku-20240307` (fastest, cheaper, less accurate)
### Rate Limiting (Future)
To implement client-side rate limiting:
```typescript
// src/lib/translation-engine.ts
const MAX_TRANSLATIONS_PER_MINUTE = 10;
```
---
## 📊 Monitoring Usage
### Anthropic Console
1. Visit: https://console.anthropic.com/settings/usage
2. View:
- Total requests
- Tokens consumed
- Cost breakdown
- Daily/monthly trends
### Set Spending Limits
1. Console → Settings → Billing
2. Set monthly limit (e.g., $50)
3. Get email alerts at 50%, 75%, 90%
---
## 🚀 Next Steps
Once you have the API key configured:
1. **Test All Translation Pairs**:
- Roblox → UEFN
- UEFN → Roblox
- Roblox → Spatial (when templates added)
2. **Share with Team**:
- Each developer needs their own API key
- Or use shared key in production only
3. **Monitor Quality**:
- Review translations for accuracy
- Report issues on GitHub
- Suggest prompt improvements
4. **Optimize Costs**:
- Cache common translations (future)
- Batch similar requests (future)
- Use cheaper model for simple code (future)
---
## 💡 Tips for Best Results
### Writing Translatable Code
Claude works best with:
- ✅ Well-commented code
- ✅ Clear variable names
- ✅ Standard patterns (no weird hacks)
- ✅ Short to medium scripts (< 500 lines)
### Using the Context Field
When translating complex code, add context:
```
Context: "This is a player spawn system that needs to work with UEFN's agent system"
```
This helps Claude understand the purpose and translate more accurately.
