Increasing Requests per minutes / Data Limit | Multiple API Keys?

In the Alpaca API Documentation it says that you are limited to 200 requests per minute per API Key, Is this Implying if you want to get faster Request speed you should make more API Keys, or is this forbidden somewhere and I have overlooked it?

Another question I was asking was Data Limits On bars being limited to 1000, But I often only get 100-200 in response. Any Idea what is causing this? Is it possible my program is messing up halfway through on a null value response or is this the APIs doing?
