+# Dataset Worker API Documentation
+
+This API allows you to manage the `dataset-worker` process from the backend via HTTP endpoints. You can start, stop, check status, view logs, and list jobs for the worker—all from the UI or other clients.
+
+## Endpoints
+
+### Start Worker
+- **POST** `/api/dataset-worker/start`
+- **Payload Example:**
+```json
+{
+  "concurrency": 2,
+  "enableScan": true,
+  "enablePack": true,
+  "enableDag": false,
+  "exitOnComplete": false,
+  "exitOnError": true,
+  "minInterval": "5s",
+  "maxInterval": "160s"
+}
+```
+- **Response:**
+```json
+{ "status": "started", "pid": 12345 }
+```
+
+### Stop Worker
+- **POST** `/api/dataset-worker/stop`
+- **Response:**
+```json
+{ "status": "stopped" }
+```
+
+### Status
+- **GET** `/api/dataset-worker/status`
+- **Response:**
+```json
+{
+  "running": true,
+  "pid": 12345,
+  "config": { ... },
+  "startTime": "2025-07-18T12:00:00Z",
+  "uptime": "2m30s"
+}
+```
+
+### Logs
+- **GET** `/api/dataset-worker/logs`
+- **Response:**
+```json
+{
+  "stdout": "Worker started...",
+  "stderr": ""
+}
+```
+
+### Jobs
+- **GET** `/api/dataset-worker/jobs`
+- **Response:**
+```json
+{
+  "jobs": [
+    { "id": 42, "type": "scan", "status": "processing", "started": "..." }
+  ]
+}
+```
+
+## Usage Notes
+- Only one worker process can run at a time.
+- All endpoints require admin privileges (add authentication as needed).
+- The jobs endpoint lists recent jobs from the database.
+- Logs are captured from the worker process's stdout/stderr.
+
+## Error Codes
+- `409 Conflict`: Worker already running
+- `404 Not Found`: Worker not running (for stop/logs)
+- `500 Internal Server Error`: Unexpected error
+
+## Example Workflow
+1. Start the worker with desired config.
+2. Monitor status and logs.
+3. Stop the worker when needed.
+4. List jobs to track progress.
+
+## Help Text
+- Each endpoint returns a clear status or error message.
+- Invalid config or requests will return a helpful error.
+
+---
+For more details, see the code in `api/dataset_worker.go` and tests in `api/dataset_worker_test.go` and `api/dataset_worker_integration_test.go`.
