Ask HN: What hard to find expensive datasets would you pay for if it were cheap?

Hi HN,

I'm building an insurance / fintech app but just realised that the cost for high quality premium datasets are really expensive.

I believe it should be brought down close to $0 and it should be usage based (if not, monthly but extremely cheap).

What really hard to find and expensive datasets should be drastically cheaper that one would pay for?

I'm on the look out for this for my insurance / fintech app.

Another thing, I really want to avoid those "Contact Sales" types, since I cannot evaluate the quality of the dataset myself.

Thanks you!
