# Quick Log Check Guide - API Endpoint Deployment

## What to Look For

When the application starts successfully, you should see these log messages **in order**:

### 1. Initial Setup (Early in startup)
```
============================================================
STARTING APP
============================================================
```

### 2. Interface Creation
```
✓ Interface created
Orchestrator available: True (or False)
```

### 3. **API Endpoint Registration** ⭐ KEY CHECKPOINT
```
✓ API endpoint '/api/safe_gpu_chat_handler' registered with api_name
```

### 4. Handler Initialization ⭐ KEY CHECKPOINT
Either:
```
✓ GPU chat handler initialized and set as API handler
```
OR
```
✓ Non-GPU chat handler initialized and set as API handler
```

### 5. Startup Verification ⭐ KEY CHECKPOINT
```
============================================================
VERIFYING API ENDPOINTS
============================================================
✓ API is enabled in Gradio config: True
Registered API endpoints:
  - /api/safe_gpu_chat_handler (POST)
  - /api/new_session (POST)
  ...
✓ API handler function initialized: True
  Handler type: function
```

### 6. Application Launch
```
============================================================
LAUNCHING GRADIO APP
============================================================
API endpoints available at: http://<host>:7860/api/
```

## Verification Checklist

- [ ] See "API endpoint '/api/safe_gpu_chat_handler' registered with api_name"
- [ ] See handler initialization message (GPU or Non-GPU)
- [ ] See "VERIFYING API ENDPOINTS" section
- [ ] See "API handler function initialized: True"
- [ ] See "API endpoints available at: http://<host>:7860/api/"

## If Logs Show Different Messages

### Missing "API endpoint registered" message
**Problem**: Endpoint might not be registered  
**Action**: Check if `api_name="safe_gpu_chat_handler"` is in the code (line 845)

### Missing handler initialization
**Problem**: Handler function might not be set  
**Action**: Check GPU availability and handler function definition

### Handler function initialized: False
**Problem**: `_api_chat_handler_fn` is None  
**Action**: Check if handlers are defined before interface creation

## Current Logs Analysis

Based on your logs:
- ✅ Application is starting ("starting up user application")
- ⏳ Need to check for Python/Gradio app logs
- ⏳ Need to see if API registration messages appear

**Next Steps**: Wait for the Python application to fully start and check for the messages above.

## Quick Test

Once you see the "LAUNCHING GRADIO APP" message, the endpoint should be accessible. You can test with:

```bash
curl -X POST https://<your-space-url>/api/safe_gpu_chat_handler \
  -H "Content-Type: application/json" \
  -d '{"data": ["test", [], "Admin_J", "Session: test | User: Admin_J | Interactions: 0"]}'
```

Expected: Response (200 or 422 = endpoint exists, 404 = not deployed)
