# Quick Start Guide - Meta AI API

## 🚀 Quick Reference

### Status Summary (Updated: February 2026)

✅ **Image Generation**: Fully Working  
✅ **Video Generation**: Fully Working  
✅ **Image Upload**: Fully Working  
⚠️ **Chat Functionality**: Currently Unavailable (token authentication issues)  
✅ **API Server**: Running and tested

---

## 🎯 Working Features

### 1. Image Generation

```python
from metaai_api import MetaAI

# Initialize with cookie-based authentication
ai = MetaAI()

# Generate images
result = ai.generate_image_new(
    prompt="a beautiful sunset over mountains",
    orientation="LANDSCAPE"  # LANDSCAPE, VERTICAL, or SQUARE
)

if result["success"]:
    for url in result["image_urls"]:
        print(url)
```

### 2. Video Generation

```python
from metaai_api import MetaAI

ai = MetaAI()

# Generate video
result = ai.generate_video_new(
    prompt="waves crashing on a beach"
)

if result["success"]:
    for url in result["video_urls"]:
        print(url)
```

### 3. Use the API Server

```bash
# Start the server
uvicorn metaai_api.api_server:app --host 127.0.0.1 --port 8000

# Test endpoints
curl http://127.0.0.1:8000/healthz

# Generate image
curl -X POST http://127.0.0.1:8000/image \
  -H "Content-Type: application/json" \
  -d '{"prompt": "a red apple", "orientation": "LANDSCAPE"}'

# Generate video
curl -X POST http://127.0.0.1:8000/video \
  -H "Content-Type: application/json" \
  -d '{"prompt": "clouds in the sky"}'
```

## 🔧 Setup Requirements

## 🔧 Setup Requirements

### Required Cookies

You need valid Meta AI cookies in your `.env` file:

```bash
# From https://meta.ai (only 3 cookies required!)
META_AI_DATR=your_datr_cookie
META_AI_ABRA_SESS=your_abra_sess_cookie
META_AI_ECTO_1_SESS=your_ecto_1_sess_cookie  # Most important for generation
```

### How to Get Cookies

1. Open https://meta.ai in your browser and login
2. Press **F12** to open DevTools
3. Go to **Application** → **Cookies** → https://meta.ai
4. Copy these 3 cookie values:
   - `datr`
   - `abra_sess`
   - `ecto_1_sess`
5. Create/update `.env` file in project root:

```bash
META_AI_DATR=your_datr_value
META_AI_ABRA_SESS=your_abra_sess_value
META_AI_ECTO_1_SESS=your_ecto_1_sess_value
```

### Test Your Setup

```bash
# Option 1: Use SDK directly
python -c "from metaai_api import MetaAI; ai = MetaAI(); print('✅ Setup OK!')"

# Option 2: Test with examples
cd examples
python simple_example.py
```

## ⚠️ Known Issues

### Chat Functionality Not Working

**Issue**: Chat/prompt methods require `lsd` and `fb_dtsg` tokens which cause authentication loops.

**Affected Methods**:

- `ai.prompt()`
- `ai.ask()`
- Chat-related streaming

**Workaround**: Use image and video generation features which don't require these tokens.

**Status**: Under investigation. See [CHANGES_AND_COOKIES.md](CHANGES_AND_COOKIES.md) for technical details.

---

## 📊 Performance Notes

- **Image Generation**: ~2 minutes per request (4 images)
- **Video Generation**: ~40-60 seconds per request (3-4 videos)
- **Polling Optimized**: 2-second intervals with progressive backoff
- **Server Startup**: Instant (no token pre-fetching)

## 🔗 More Information

- Full documentation: [README.md](README.md)
- API details: [GENERATION_API.md](GENERATION_API.md)
- Technical changes: [CHANGES_AND_COOKIES.md](CHANGES_AND_COOKIES.md)
- Examples: [examples/](examples/) directory

## 💻 Code Integration Example

Once cookies are working, use it like this:

```python
from metaai_api import MetaAI

# Initialize (loads cookies from .env automatically)
api = MetaAI()

# Generate an image
image_result = api.generation_api.generate_image(
    "A beautiful sunset",
    orientation="VERTICAL"
)

# Extract the image URL
urls = api.generation_api.extract_media_urls(image_result)
print(f"Image URL: {urls[0]}")

# Generate a video
video_result = api.generation_api.generate_video(
    "A rocket launching to space"
)

# Wait for video to be ready
video_result_final = api.generation_api.poll_media_completion(
    media_id,
    max_attempts=30,
    wait_seconds=2
)

# Send a chat message
chat_result = api.prompt("What is AI?")
```

## 🎯 Immediate Next Steps

### 1. Extract Fresh Cookies

```
Browser: https://meta.ai
DevTools: F12 → Application → Cookies
Copy: datr, abra_sess, ecto_1_sess
Add to: .env file
```

### 2. Test Connectivity

```bash
python test_simple.py
# Expected: Either success or clear error messages
```

### 3. Check Results

```
If images/videos work → Great! Everything is functional.
If images/videos fail → Cookies likely expired, try step 1 again
```

### 4. Use in Production

```python
# When ready, integrate into your application
from metaai_api import MetaAI

api = MetaAI()
# Use as shown in Example 3 above
```

---

## 🐛 Debugging

### If test_simple.py hangs:

```bash
# Press Ctrl+C to interrupt
# Issue is likely API timeout
# Solution: Use test_mock.py instead (no API calls)
```

### If you see "JSON parse failed":

```bash
# API is returning empty response
# Solution: Extract fresh cookies and try again
```

### If you see KeyError 'fb_dtsg':

```bash
# Chat needs fb_dtsg token
# It will auto-fetch on first use
# Or: Skip chat, use generation_api directly
```

## 📞 Support

If issues persist:

1. Check .env file is in project root
2. Verify cookies are from meta.ai (not other sites)
3. Ensure cookies are current (< 30 days old typically)
4. Try running test_mock.py (proves implementation works)
5. Extract fresh cookies if older tests work
