Alpaca the best data source for derivatives? Is it the paid model?

I've been using yfinance to screen for high ROI puts, but the data doesn't seem to be reliable. I tried using the options bar API in Alpaca but it retrieves empty lists (I think I must need the paid model, but dont want to pay if it's not going to work).

Is anybody using a reliable API to get bought / sold daily contract info for a ticker? Some of the API's I've seen that claim to do it seems to be complex. The contract chains have to be crawled and it seems to be indexed by expiration date - making it difficult to look for things bought and sold today or... in the last hour..

Is anybody doing this using something reliable? I dont mind paying for API access, I just dont want to pay for something that is unreliable..
