# 🔍 Find Your Correct API URL - 404 Troubleshooting
## 🚨 **Your Space is giving 404 errors - Let's find the right URL!**
### **Step 1: Check Your Space Status**
1. **Go to your Space directly**: https://huggingface.co/spaces/CarsaAI/carsa_api
2. **Look for these indicators:**
- ✅ **"Running"** status (green)
- ❌ **"Building"** status (yellow)
- ❌ **"Runtime Error"** status (red)
- ❌ **"Stopped"** status (gray)
### **Step 2: If Your Space Shows "Running", Try These URLs:**
#### **URL Format 1:**
```
https://carsaai-carsa-api.hf.space
```
#### **URL Format 2 (with port):**
```
https://carsaai-carsa-api.hf.space:7860
```
#### **URL Format 3 (alternative naming):**
```
https://carsa-ai-carsa-api.hf.space
```
#### **URL Format 4 (proxy path):**
```
https://huggingface.co/spaces/CarsaAI/carsa_api/proxy
```
#### **URL Format 5 (direct embed):**
```
https://carsaai-carsa-api.hf.space/health
```
### **Step 3: Test URLs in Your Browser**
**Open each URL in your browser and look for:**
✅ **Working URL will show:**
```json
{
"status": "Carsa AI API is running",
"version": "1.0.0",
"services": ["translation", "speech-to-text", "text-to-speech"]
}
```
❌ **404 Error will show:**
```
404 - Sorry, we can't find the page you are looking for.
```
### **Step 4: If ALL URLs Give 404**
Your Space might not be properly deployed. Check these:
#### **A. Check Space Logs:**
1. Go to: https://huggingface.co/spaces/CarsaAI/carsa_api
2. Click **"Logs"** tab
3. Look for errors in the build/runtime logs
#### **B. Common Issues:**
- **Build Failed**: Space never started properly
- **Runtime Error**: Space started but crashed
- **Port Issues**: App running on wrong port
- **Branch Issues**: Code not on correct branch
#### **C. Force Rebuild:**
1. Go to your Space settings
2. Click **"Restart this Space"**
3. Wait for rebuild to complete
### **Step 5: Alternative URLs to Try**
If the standard format doesn't work, your Space might use:
```
https://hf.space/carsaai/carsa_api
https://spaces.huggingface.co/CarsaAI/carsa_api
https://carsaai-carsa-api.hf.space/gradio_api/health
```
### **Step 6: Quick Debug Test**
**Test this simple URL in your browser:**
```
https://carsaai-carsa-api.hf.space/docs
```
If this works, you'll see the **FastAPI documentation page**.
### **Step 7: Update Your Flutter App**
Once you find the working URL, update your Flutter `api_service.dart`:
```dart
class ApiService {
// Replace with the URL that works from Step 2-3
static const String baseUrl = 'YOUR_WORKING_URL_HERE';
// Test translation endpoint
static Future<void> testConnection() async {
try {
final response = await http.get(Uri.parse('$baseUrl/health'));
print('✅ Connection test: ${response.statusCode}');
print('✅ Response: ${response.body}');
} catch (e) {
print('❌ Connection failed: $e');
}
}
}
```

## 🎯 **IMMEDIATE ACTIONS:**
