    # https://requests.readthedocs.io/en/master/user/advanced/#session-objects
    with RESTClient(key) as client:
        resp = client.stocks_equities_daily_open_close("AAPL", "2018-03-02")
        print(f"On: {resp.from_} Apple opened at {resp.open} and closed at {resp.close}")


if __name__ == '__main__':
    main()

Notes about the REST Client

We use swagger as our API spec and we used this swagger to generate most of the code that defines the REST client. We made this decision due to the size of our API, many endpoints and object definitions, and to accommodate future changes.
