Unable to Request Historical data from > ~8 months ago

New here. I am attempting to access historical data via the REST API. If it matters, I am currently not using any web/data sockets, I believe everything is coming/going as HTTP requests. I can pull in recent data just fine, but if I attempt to pull older data ( > ~8 months ago) the request returns nothing.

If it matters, I am using Python, API version V2, attempting to pull minute-by-minute bars within market hours, and I have a free account. I have updated my code to pull hourly/daily data and it still returns nothing.

I suspect it may be that I do not have a paid-subscription account. If I start paying for the service, will I have access to this data?
