+
+## Base URL
+```
+http://localhost:5002
+```
+
+## Endpoints
+
+### 1. Health Check
+**GET** `/health`
+
+Check if the API is running and model is loaded.
+
+**Response:**
+```json
+{
+  "status": "healthy",
+  "model_loaded": true,
+  "timestamp": "2025-07-12T07:41:46.123456"
+}
+```
+
+### 2. API Information
+**GET** `/api`
+
+Get basic API information and available endpoints.
+
+**Response:**
+```json
+{
+  "name": "Memory Module Detection API",
+  "version": "1.0",
+  "description": "AI-powered memory module detection using YOLOv8",
+  "model_loaded": true,
+  "endpoints": ["/health", "/api", "/detect", "/detect/hardcoded", "/detect/base64"]
+}
+```
+
+### 3. Upload Image Detection
+**POST** `/detect`
+
+Upload an image file for memory module detection.
+
+**Request:**
+- Content-Type: `multipart/form-data`
+- Body: Form data with `file` field containing image
+- Optional: `confidence` parameter (default: 0.8)
+
+**Response:**
+```json
+{
+  "success": true,
+  "detections": [
+    {
+      "x1": 100.5,
+      "y1": 150.2,
+      "x2": 200.8,
+      "y2": 250.6,
+      "confidence": 0.95,
+      "class": "memory_module"
+    }
+  ],
+  "num_detections": 1,
+  "annotated_image": "base64_encoded_image_string",
+  "confidence_threshold": 0.8
+}
+```
+
+### 4. Hardcoded Test Image
+**GET** `/detect/hardcoded`
+
+Process the hardcoded test image for detection.
+
+**Query Parameters:**
+- `confidence` (optional): Confidence threshold (default: 0.8)
+
+**Example:**
+```
+GET /detect/hardcoded?confidence=0.9
+```
+
+**Response:**
+```json
+{
+  "success": true,
+  "detections": [...],
+  "num_detections": 2,
+  "annotated_image": "base64_encoded_image_string",
+  "confidence_threshold": 0.9,
+  "test_image_path": "training/memory/out1.png"
+}
+```
+
+### 5. Base64 Image Detection
+**POST** `/detect/base64`
+
+Process a base64 encoded image for detection.
+
+**Request:**
+```json
+{
+  "image_data": "base64_encoded_image_string",
+  "confidence": 0.8
+}
+```
+
+**Response:**
+```json
+{
+  "success": true,
+  "detections": [...],
+  "num_detections": 1,
+  "annotated_image": "base64_encoded_image_string",
+  "confidence_threshold": 0.8
+}
+```
+
+## Error Responses
+
+All endpoints return error responses in this format:
+```json
+{
+  "error": "Error message description",
+  "success": false
+}
+```
+
+Common HTTP status codes:
+- `200` - Success
+- `400` - Bad Request (invalid file, missing parameters)
+- `404` - Not Found (endpoint or file not found)
+- `413` - File Too Large (max 16MB)
+- `500` - Internal Server Error (model not loaded, processing error)
+
+## Supported Image Formats
+- PNG
+- JPG/JPEG
+- GIF
+- BMP
+
+## File Size Limits
+- Maximum upload size: 16MB
+
+## Detection Response Format
+
+Each detection object contains:
+- `x1, y1`: Top-left corner coordinates
+- `x2, y2`: Bottom-right corner coordinates  
+- `confidence`: Detection confidence score (0.0-1.0)
+- `class`: Detected object class ("memory_module")
+
+## Usage Examples
+
+### cURL Examples
+
+**Health Check:**
+```bash
+curl http://localhost:5002/health
+```
+
+**Upload Image:**
+```bash
+curl -X POST -F "file=@image.jpg" -F "confidence=0.8" http://localhost:5002/detect
+```
+
+**Hardcoded Test:**
+```bash
+curl "http://localhost:5002/detect/hardcoded?confidence=0.9"
+```
+
+### Python Examples
+
+**Health Check:**
+```python
+import requests
+
+response = requests.get('http://localhost:5002/health')
+print(response.json())
+```
+
+**Upload Image:**
+```python
+import requests
+
+with open('image.jpg', 'rb') as f:
+    files = {'file': f}
+    data = {'confidence': 0.8}
+    response = requests.post('http://localhost:5002/detect', files=files, data=data)
+    print(response.json())
+```
+
+**Base64 Detection:**
+```python
+import requests
+import base64
+
+with open('image.jpg', 'rb') as f:
+    image_data = base64.b64encode(f.read()).decode()
+
+payload = {
+    'image_data': image_data,
+    'confidence': 0.8
+}
+response = requests.post('http://localhost:5002/detect/base64', json=payload)
+print(response.json())
+```
