You're not going to pollute VISA/Mastercard without running afoul of identity theft/wire fraud charges in the United States.

Any other datasets are only going to attempt to "enrich" their own datasets with other datasets. This is why Plaid* had such a strong value proposition in spite of their completely unethical business practices.
