Looks good! I would just say add some more endpoints and questions. A requirement is there should be at least 5 endpoints per website and at least 1 question per endpoint being added. If one of the websites has fewer than 5 endpoints then can just make minimum 3 questions for the website and one config file per endpoint and mention the number of enpoints the API has. Good job!
