+# API Endpoint Verification Guide
+
+## Overview
+
+This document explains how to verify that the `api_name="safe_gpu_chat_handler"` endpoint is properly deployed and running.
+
+## Implementation Status
+
+✅ **Code Deployed**: The API endpoint registration code is present in `app.py`:
+- Line 845: `api_name="safe_gpu_chat_handler"` is set on the `api_message.submit()` event
+- Line 849: Log message confirms registration
+- Lines 1899-1900, 2002-2003: Handler functions are initialized and set globally
+- Lines 2073-2097: Verification logging on app startup
+
+## Verification Methods
+
+### 1. Check Application Logs
+
+When the application starts, you should see these log messages:
+
+```
+============================================================
+VERIFYING API ENDPOINTS
+============================================================
+✓ API is enabled in Gradio config: True
+Registered API endpoints:
+  - /api/safe_gpu_chat_handler (POST)
+  - /api/new_session (POST)
+  - /api/update_session_info (POST)
+  ...
+✓ API handler function initialized: True
+  Handler type: function
+============================================================
+LAUNCHING GRADIO APP
+============================================================
+API endpoints available at: http://<host>:7860/api/
+```
+
+Additionally, during interface creation:
+```
+✓ API endpoint '/api/safe_gpu_chat_handler' registered with api_name
+✓ GPU chat handler initialized and set as API handler
+```
+OR
+```
+✓ Non-GPU chat handler initialized and set as API handler
+```
+
+### 2. Use the Verification Script
+
+Run the verification script to test the endpoint:
+
+```bash
+python verify_api_endpoint.py [base_url]
+```
+
+Example:
+```bash
+# Local testing
+python verify_api_endpoint.py http://localhost:7860
+
+# HuggingFace Spaces
+python verify_api_endpoint.py https://jatinautonomouslabs-research-ai-assistant.hf.space
+```
+
+The script will:
+- Check if Gradio API info is accessible
+- Verify the endpoint is registered
+- Test actual endpoint accessibility
+- Return exit code 0 if successful
+
+### 3. Manual HTTP Test
+
+Test the endpoint directly using curl or HTTP client:
+
+```bash
+curl -X POST http://localhost:7860/api/safe_gpu_chat_handler \
+  -H "Content-Type: application/json" \
+  -d '{
+    "data": [
+      "test message",
+      [],
+      "Admin_J",
+      "Session: test123 | User: Admin_J | Interactions: 0"
+    ]
+  }'
+```
+
+Expected responses:
+- **200 OK**: Endpoint is working correctly
+- **422 Validation Error**: Endpoint exists but validation failed (still confirms deployment)
+- **404 Not Found**: Endpoint not registered
+
+### 4. Check Gradio API Documentation
+
+Visit the Gradio API documentation page:
+- Local: `http://localhost:7860/docs` or `http://localhost:7860/api/docs`
+- Spaces: `https://<your-space>.hf.space/docs`
+
+Look for `/api/safe_gpu_chat_handler` in the list of available endpoints.
+
+### 5. Inspect Gradio Config
+
+If you have access to the running instance, check:
+
+```python
+import gradio as gr
+# After demo is created
+demo.config.api_open  # Should be True
+demo.config.show_api  # Should be True
+```
+
+## Code Location Reference
+
+| Component | File | Line(s) |
+|-----------|------|---------|
+| API Endpoint Registration | `app.py` | 838-849 |
+| Handler Initialization (GPU) | `app.py` | 1899-1900 |
+| Handler Initialization (Non-GPU) | `app.py` | 2002-2003 |
+| Startup Verification | `app.py` | 2073-2097 |
+| Global Handler Variable | `app.py` | 27-28 |
+
+## Troubleshooting
+
+### Issue: Endpoint not found (404)
+
+**Check:**
+1. Application logs show "API endpoint registered" message
+2. `show_api=True` is set in `demo.launch()` (line 2108)
+3. Handler function is initialized (check logs for handler type)
+
+**Solution:**
+- Ensure `api_name` parameter is correctly set on the submit event
+- Verify the handler function is defined before the interface is created
+
+### Issue: Handler function is None
+
+**Check:**
+1. Logs show handler initialization message
+2. `_api_chat_handler_fn` is set after handlers are defined
+
+**Solution:**
+- Verify GPU availability check runs correctly
+- Check that handler functions are defined (lines 1779-1997)
+
+### Issue: Endpoint accessible but returns errors
+
+**This is expected** - The endpoint is deployed correctly. The errors are validation or processing errors, not deployment issues.
+
+## Expected Behavior
+
+✅ **Deployed Successfully**:
+- Application logs show registration messages
+- HTTP requests to `/api/safe_gpu_chat_handler` return 200 or 422 (not 404)
+- Verification script passes
+- Handler function is not None
+
+❌ **Not Deployed**:
+- 404 errors on endpoint access
+- Logs don't show registration messages
+- Handler function is None
+
+## Additional Notes
+
+- The endpoint uses hidden Gradio components (visible=False) to avoid UI interference
+- The handler automatically selects GPU or non-GPU handler based on availability
+- Fallback to `process_message` ensures endpoint always works
+- All API endpoints are registered with `api_name` parameters for REST access
