+# RDC REST API
+
+## Overview
+This REST API provides functionalities to:
+- Discover available GPUs on a node.
+- Configure and manage GPU monitoring queries.
+- Retrieve GPU metrics based on configured queries.
+
+The API is built using Flask and interacts with the RDC library to monitor GPU usage and performance metrics.
+
+## Installation
+### Prerequisites
+- Python 3.x
+- Flask
+- RDC Library (`librdc_bootstrap.so` must be available and accessible)
+
+### Install Dependencies
+```sh
+pip install flask
+```
+
+## Running the API
+1. Ensure `librdc_bootstrap.so` is in the library path:
+   ```sh
+   export LD_LIBRARY_PATH=/path/to/librdc_bootstrap.so:$LD_LIBRARY_PATH
+   ```
+2. Run the API:
+   ```sh
+   python rdc_rest_api.py
+   ```
+
+The API will start and listen on `http://0.0.0.0:50052`.
+
+## API Endpoints
+
+### 1. Discover GPUs
+**GET** `/rdc/discovery`
+#### Response:
+```json
+{
+  "0": "GPU Name",
+  "1": "GPU Name"
+}
+```
+
+### 2. Create Query Criteria
+**POST** `/rdc/query_criteria`
+#### Request Body:
+```json
+{
+  "gpu_index": [0,1],
+  "metrics": ["RDC_FI_GPU_CLOCK", "RDC_FI_GPU_TEMP"]
+}
+```
+#### Response:
+```json
+{
+  "query_id": "G-1-F-2"
+}
+```
+
+### 3. Get Query Criteria
+**GET** `/rdc/query_criteria/<query_id>`
+#### Response:
+```json
+{
+  "gpu_index": [0,1],
+  "metrics": ["RDC_FI_GPU_CLOCK", "RDC_FI_GPU_TEMP"],
+  "query_id": "G-1-F-2"
+}
+```
+
+### 4. Delete Query Criteria
+**DELETE** `/rdc/query_criteria/<query_id>`
+#### Response:
+```json
+{
+  "message": "Deleted successfully"
+}
+```
+
+### 5. Retrieve GPU Metrics
+**GET** `/rdc/gpu_metrics/<query_id>`
+#### Response:
+```json
+[
+  {
+    "gpu_index": 0,
+    "RDC_FI_GPU_CLOCK": 1450,
+    "RDC_FI_GPU_TEMP": 32
+  },
+  {
+    "gpu_index": 1,
+    "RDC_FI_GPU_CLOCK": 736,
+    "RDC_FI_GPU_TEMP": 35
+  }
+]
+```
+
+## Notes
+- Ensure `librdc_bootstrap.so` is properly linked.
+- The API should be run on a system with RDC installed and GPUs accessible.
