Datasets

Hi everyone,

I’m working on a project where I need to build an automated system that can determine the price of a cryptocurrency at the exact time a client’s transaction occurred. The idea is simple: for each transaction, take the coin and timestamp, and fetch the corresponding USD price at that moment.

For this, I’m looking for datasets that provide historical cryptocurrency prices

• Coin name or symbol
• Timestamp of the price
• Price in USD

Minute-level resolution or better would be ideal, as cryptocurrency prices can fluctuate rapidly. Datasets can be in CSV, JSON, Parquet. It would be great if the data covers a wide range of coins, not just Bitcoin or Ethereum, since client transactions could involve altcoins as well.

If anyone has access to such datasets, whether public, private, or via an API, I’d greatly appreciate it if you could share it. Any tips on working with large historical crypto datasets efficiently would also be helpful.

The goal is to make a system that can automatically take a client’s transaction and return the exact price at that moment, so having accurate historical price data is essential.

Thanks in advance for any help or guidance!
