Request for feedback on providers for options data

[AdyGtl]

Hi everyone,

I am currently in the process of searching for an alternative to Bloomberg. I have written a couple of scripts in BQuant which I would like to reproduce in the new solution (once selected). All of them are dedicated to market screening for investment strategies.

The most challenging part is to retrieve option data. When coming accross OpenBB, I found this information on option chain https://docs.openbb.co/platform/reference/derivatives/options/chains
which is exactly what I'm looking for.

If I understand correctly the way OpenBB is working, I have to subscribe to data providers to obtain an API key. Note that paying a subscription is not a problem in this particular case as I'm not necessarily looking for a free API.

I would like to know if some of you have some experience to share on the various data providers.
I have looked at the different websites and not sure about the information I have collected.

For example, CBOE seems not to accept new subscriptions ?
Intrinio seems complete but is almost as expansive as our current Bloomberg license.
Regarding Tradier, it's not clear whether we would have to open a brokerage account to access API, and if this is the case I expect some hidden fees.
Finally, I have already tried the Yahoo Finance (through Python lib) and results did not seem accurate (almost no bid price when compared to my BBG output).

Screening options can imply a high volume of data, has anyone faced some limitation issues ?

I would be happy to read some experience and to share mine.
