+
+Currently supports API version 2.
+
+## Usage

+1. define the `update_request.yaml` as follow:
+
+```yaml
+# adjust the settings as your needs
+- ecu_id: "autoware"
+  version: "789.x"
+  url: "https://10.0.1.1:8443/"
+  cookies: '{"test": "my-cookie"}'
+```
+
+1. make the OTA update request API call as follow:
+
+```shell
+ python3 tools/local_ota/api_v2 -i 10.0.1.10 update_request.yaml
+```
