You can certainly use the Tradier API to do this. For delayed data you can use the Developer Sandbox for request/response.

You can find the streaming documentation here: https://developer.tradier.com/documentation/streaming/get-markets-events

I've run into this issue as well. I can't find any official documentation, but the issue arises because the SEC makes up CUSIPs for all of the options on the list. It does this by taking the first 6 digits of the underlying equity (which makes sense, as this represents the issuer, which should be the same for the stock and the option), and then for the 7th ...

Here is a list of vendors connected to OPRA directly who can supply such data. http://www.opradata.com/related_info/vendor_list.jsp Like yourself I looked at Xignite.
