# API Configuration Complete ✓

## Summary of Changes

I've successfully fixed the API integration issues in Supervertaler:

### 1. **API Keys Path Fixed** ✅
- Updated `load_api_keys()` to check `user data_private/api_keys.txt` **first**
- Falls back to root `api_keys.txt` if not found
- Your API keys in `user data_private/api_keys.txt` are now being loaded correctly

### 2. **Google Cloud Translation API Implemented** ✅
- **Removed**: Broken `googletrans` library (unmaintained, causes httpcore errors)
- **Added**: Official `google-cloud-translate` library
- **Installed**: `pip install google-cloud-translate` ✓
- Now uses paid Google Cloud Translation API with your API key

### 3. **Dependencies Fixed** ✅
- **httpx**: Upgraded to 0.27.2 (fixes BaseTransport import error)
- **openai**: Updated to >= 1.0.0
- **anthropic**: Updated to >= 0.21.0
- **google-cloud-translate**: Installed for paid MT service
- **deepl**: Already installed

## Current API Keys Status

From your `user data_private/api_keys.txt`:

| API Service | Status | Key Preview |
|-------------|--------|-------------|
| **Google (Gemini)** | ✓ Configured | AIzaSyDgz9...f6HLE |
| **Claude** | ✓ Configured | sk-ant-api...O7AAA |
| **OpenAI** | ✓ Configured | sk-proj-9K...bOFcA |
| **DeepL** | ⚠️ Invalid | 47e36ca1-2...f8fa5 |
| **Google Translate** | ✗ Missing | Not configured |

---

## Next Steps

### 1. Add Google Cloud Translation API Key

You mentioned you have a **paid Google Translate API key**. Add it to your `api_keys.txt`:

```bash
# user data_private/api_keys.txt
google_translate = YOUR_GOOGLE_CLOUD_TRANSLATE_API_KEY_HERE
```

**How to get the key:**
1. Go to: https://console.cloud.google.com/apis/credentials
2. Enable "Cloud Translation API" in your project
3. Create an API key (or use existing one)
4. Copy the key to `api_keys.txt`

### 2. Fix DeepL API Key

Your current DeepL key shows error: "This account is not allowed to access the API"

**This means:**
- The key is for DeepL's **free web translation** (not API access)
- You need a **DeepL API Pro** account to use the API

**Options:**
1. Get DeepL API key from: https://www.deepl.com/pro-api
2. Or remove DeepL from MT options (Google Translate works well)

## API Integration Features

### memoQ-Style Auto-Updating MT Preview

When you select a segment, the MT panel automatically updates after 2 seconds:

1. **Google Cloud Translation** - Uses your paid API key
2. **DeepL** - Uses your API key (once fixed)
3. **LLM Translation** - Uses OpenAI/Claude/Gemini

### In-Place Updates (No Screen Refresh)

When you press **Ctrl+T** to translate:
- Target text updates immediately
- Segment selection preserved
- No screen flicker or jump
- Just like memoQ/Trados workflow

### Real Fuzzy Matching

Database now uses `SequenceMatcher` for accurate similarity:
- Test results: 81%, 72%, 64%, 73% match scores
- FTS5 full-text search with special character handling
- No more syntax errors with commas or quotes

---

## Testing the Application

### Quick Start Test

```bash
cd "c:\Dev\Supervertaler"
python Supervertaler_v3.7.2.py
```

### What Should Work Now

1. ✅ Application starts (no more httpx errors)
2. ✅ API keys loaded from `user data_private/api_keys.txt`
3. ✅ TM Manager opens without errors
4. ✅ Translate Current Segment (Ctrl+T) works
5. ✅ Auto-updating resource panels (2-second delay)
6. ⚠️ Google Translate needs API key
7. ⚠️ DeepL needs valid API key
8. ✅ LLM previews work (OpenAI/Claude/Gemini)

### Test Workflow

1. Open a project
2. Select a segment
3. Wait 2 seconds → MT/LLM panels update automatically
4. Press **Ctrl+T** → Target updates in-place
5. Check TM matches → Real fuzzy scores displayed

---

## Troubleshooting

### If Google Translate shows error:
```
[Google Cloud Translation requires API key in api_keys.txt: google_translate=YOUR_KEY]
```
→ Add `google_translate = YOUR_KEY` to `user data_private/api_keys.txt`

### If DeepL shows authorization error:
```
Authorization failure, check auth_key
```
→ Get DeepL API Pro key from https://www.deepl.com/pro-api

### If application won't start:
```bash
# Check dependencies
pip list | findstr "httpx openai anthropic"

# Should show:
# httpx         0.27.2
# openai        1.x.x
# anthropic     0.21.x
```
