    You can create SerpApi.com key by signing up at: https://serpapi.com/users/sign_up.
    The wrapper uses the SerpApi.com python package:
    https://serpapi.com/integrations/python
    To use, you should have the environment variable ``SERPAPI_API_KEY``
    set with your API key, or pass `serp_api_key` as a named parameter
    to the constructor.
     Example:
        .. code-block:: python
        from langchain_community.utilities import GoogleJobsAPIWrapper
        google_Jobs = GoogleJobsAPIWrapper()
        google_Jobs.run('langchain')
