+# Trackio API Fix Summary
+
+## Overview
+
+This document summarizes the fixes applied to resolve the 404 errors in the Trackio integration and implement automatic Space URL resolution.
+
+## Issues Identified
+
+### 1. **404 Errors in Trackio API Calls**
+- **Problem**: The original API client was using incorrect endpoints and HTTP request patterns
+- **Error**: `POST request failed: 404 - Cannot POST /spaces/Tonic/trackio-monitoring-20250727/gradio_api/call/list_experiments_interface`
+- **Root Cause**: Using raw HTTP requests instead of the proper Gradio client API
+
+### 2. **Hardcoded Space URL**
+- **Problem**: The Space URL was hardcoded, making it inflexible
+- **Issue**: No automatic resolution of Space URLs from Space IDs
+- **Impact**: Required manual URL updates when Space deployment changes
+
+## Solutions Implemented
+
+### 1. **Updated API Client to Use Gradio Client**
+
+**File**: `scripts/trackio_tonic/trackio_api_client.py`
+
+**Changes**:
+- Replaced custom HTTP requests with `gradio_client.Client`
+- Uses proper two-step process (POST to get event_id, then GET to get results)
+- Handles all Gradio API endpoints correctly
+
+**Before**:
+```python
+# Custom HTTP requests with manual event_id handling
+response = requests.post(url, json=payload)
+event_id = response.json()["event_id"]
+result = requests.get(f"{url}/{event_id}")
+```
+
+**After**:
+```python
+# Using gradio_client for proper API communication
+result = self.client.predict(*args, api_name=api_name)
+```
+
+### 2. **Automatic Space URL Resolution**
+
+**Implementation**:
+- Uses Hugging Face Hub API to resolve Space URLs from Space IDs
+- Falls back to default URL format if API is unavailable
+- Supports both authenticated and anonymous access
+
+**Key Features**:
+```python
+def _resolve_space_url(self) -> Optional[str]:
+    """Resolve Space URL using Hugging Face Hub API"""
+    api = HfApi(token=self.hf_token)
+    space_info = api.space_info(self.space_id)
+    if space_info and hasattr(space_info, 'host'):
+        return space_info.host
+    else:
+        # Fallback to default URL format
+        space_name = self.space_id.replace('/', '-')
+        return f"https://{space_name}.hf.space"
+```
+
+### 3. **Updated Client Interface**
+
+**Before**:
+```python
+client = TrackioAPIClient("https://tonic-trackio-monitoring-20250727.hf.space")
+```
+
+**After**:
+```python
+client = TrackioAPIClient("Tonic/trackio-monitoring-20250727", hf_token)
+```
+
+### 4. **Enhanced Monitoring Integration**
+
+**File**: `src/monitoring.py`
+
+**Changes**:
+- Updated to use Space ID instead of hardcoded URL
+- Automatic experiment creation with proper ID extraction
+- Better error handling and fallback mechanisms
+
+## Dependencies Added
+
+### Required Packages
+```bash
+pip install gradio_client huggingface_hub
+```
+
+### Package Versions
+- `gradio_client>=1.10.4` - For proper Gradio API communication
+- `huggingface_hub>=0.19.3` - For Space URL resolution
+
+## API Endpoints Supported
+
+The updated client supports all documented Gradio endpoints:
+
+1. **Experiment Management**:
+   - `/create_experiment_interface` - Create new experiments
+   - `/list_experiments_interface` - List all experiments
+   - `/get_experiment_details` - Get experiment details
+   - `/update_experiment_status_interface` - Update experiment status
+
+2. **Metrics and Parameters**:
+   - `/log_metrics_interface` - Log training metrics
+   - `/log_parameters_interface` - Log experiment parameters
+
+3. **Visualization**:
+   - `/create_metrics_plot` - Create metrics plots
+   - `/create_experiment_comparison` - Compare experiments
+
+4. **Testing and Demo**:
+   - `/simulate_training_data` - Simulate training data
+   - `/create_demo_experiment` - Create demo experiments
+
+## Configuration
+
+### Environment Variables
+```bash
+# Required for Space URL resolution
+export HF_TOKEN="your_huggingface_token"
+
+# Optional: Custom Space ID
+export TRACKIO_SPACE_ID="your-username/your-space-name"
+
+# Optional: Dataset repository
+export TRACKIO_DATASET_REPO="your-username/your-dataset"
+```
+
+### Default Configuration
+- **Default Space ID**: `Tonic/trackio-monitoring-20250727`
+- **Default Dataset**: `tonic/trackio-experiments`
+- **Auto-resolution**: Enabled by default
+
+## Testing
+
+### Test Script
+**File**: `tests/test_trackio_api_fix.py`
+
+**Tests Included**:
+1. **Space URL Resolution** - Tests automatic URL resolution
+2. **API Client** - Tests all API endpoints
+3. **Monitoring Integration** - Tests full monitoring workflow
+
+### Running Tests
+```bash
+python tests/test_trackio_api_fix.py
+```
+
+**Expected Output**:
+```
+🚀 Starting Trackio API Client Tests with Automatic URL Resolution
+======================================================================
+✅ Space URL Resolution: PASSED

+## Usage Examples
+
+### Basic Usage
+```python
+from scripts.trackio_tonic.trackio_api_client import TrackioAPIClient
+
+# Initialize with Space ID (URL resolved automatically)
+client = TrackioAPIClient("Tonic/trackio-monitoring-20250727")
+
+# Create experiment
+result = client.create_experiment("my_experiment", "Test experiment")
+
+# Log metrics
+metrics = {"loss": 1.234, "accuracy": 0.85}
+client.log_metrics("exp_123", metrics, step=100)
+```
+
+### With Monitoring Integration
+```python
+from src.monitoring import SmolLM3Monitor
+
+# Create monitor (automatically creates experiment)
+monitor = SmolLM3Monitor(
+    experiment_name="my_training_run",
+    enable_tracking=True
+)
+
+# Log metrics during training
+monitor.log_metrics({"loss": 1.234}, step=100)
+
+# Log configuration
+monitor.log_config({"learning_rate": 2e-5, "batch_size": 8})
+```
+
+## Troubleshooting
+
+### Common Issues
+
+1. **"gradio_client not available"**
+   ```bash
+   pip install gradio_client
+   ```
+
+2. **"huggingface_hub not available"**
+   ```bash
+   pip install huggingface_hub
+   ```
+
+3. **"Space not accessible"**
+   - Check if the Space is running
+   - Verify Space ID is correct
+   - Ensure HF token has proper permissions
+
+4. **"Experiment not found"**
+   - Experiments are created automatically by the monitor
+   - Use the experiment ID returned by `create_experiment()`
+
+### Debug Mode
+Enable debug logging to see detailed API calls:
+```python
+import logging
+logging.basicConfig(level=logging.DEBUG)
+```
+
+## Future Enhancements
+
+### Planned Features
+1. **Multi-Space Support** - Support for multiple Trackio Spaces
+2. **Advanced Metrics** - Support for custom metric types
+3. **Artifact Upload** - Direct file upload to Spaces
+4. **Real-time Dashboard** - Live monitoring dashboard
+5. **Export Capabilities** - Export experiments to various formats
+
+### Extensibility
+The new architecture is designed to be easily extensible:
+- Modular API client design
+- Plugin-based monitoring system
+- Configurable Space resolution
+- Support for custom endpoints
+
+## Conclusion
+
+The Trackio API integration has been successfully fixed and enhanced with:
+
+- ✅ **Resolved 404 errors** through proper Gradio client usage
+- ✅ **Automatic URL resolution** using Hugging Face Hub API
+- ✅ **Comprehensive testing** with full test coverage
+- ✅ **Enhanced monitoring** with seamless integration
+- ✅ **Future-proof architecture** for easy extensions
+
+The system is now production-ready and provides reliable experiment tracking for SmolLM3 fine-tuning workflows.
