In a similar boat. Would like historical bid/ask if possible and live bid/ask (not 15 min delay). Willing to pay if it's not hundreds per month.

I got them from InteractiveBrokers a while back. It was definitely not hundreds per month, more like 15/mo

I bought historical option data in the past directly from CBOE [0]. Depending on what you need the prices are very reasonable. E.g. for a single symbol ~$70-$80 for a year depending on the interval you need. There is a big discount if you just buy all the symbols.

I cannot recommend the stock prices though. Somehow there were just a lot of mistakes and you can get them from other sources cheaper.

TD's API supports option chains. They don't have a good first party Python library, but it's pretty straight forward.

IEX only does end of day pricing and even that is delayed until the next day.
