-This endpoint adheres to the POST method requirement and returns a list of towns in Cameroun. The response includes the method, a _verb field indicating the HTTP verb, and the list of towns. It follows the provided code structure and examples.
\ No newline at end of file
+This code defines a list of towns in Cameroun, then creates a FastAPI router with a single POST endpoint at `/open`. When this endpoint is called with a POST request, it returns the list of towns along with the request method metadata.
+
+If the request is made with any HTTP method other than POST, it will raise a 405 Method Not Allowed error.
+
+The response format adheres strictly to the provided examples, including the `method`, `_verb`, and nested data structure under the `towns` key.
