Can you purchase just data?

I'm curious to understand your perspective on the concept of purchasing just data in the context of cryptocurrency and finance. Is it feasible to buy data as a standalone product, or is it typically bundled with other services or assets? And if it is possible to purchase data, how does one ensure the authenticity, quality, and security of the data being acquired? Additionally, are there any specific regulations or legal considerations that one should be aware of when engaging in such transactions? I'm eager to learn more about this intriguing idea.
