Hi! I'm trying to find certain bitcoin data down to 1-minute resolution and I'm not having much luck, unfortunately. Honestly if you can beat an hour resolution, I'll be super happy, and I'm trying to go back to May 2016 or so.
I need transaction volume in BTC, mempool size in BTC, and transaction fees (I don't really care what the metric is here, as long as it's consistent- transaction fee for 90% chance of making it in the next 30 minutes would work, minimum transaction fee in last block would work.... etc).
Blockchain.info is only giving me 1-day resolution for some of these when I ask for one-second, and I've done a good amount of googling. Anything you can suggest would be welcome. I will send a small reward if someone can find me all three :3
I found this when I was researching for a project I'm brainstorming, put it on my todo list. Haven't looked at it but here's the links:

Here's where I found it: https://stackoverflow.com/questions/16143266/get-bitcoin-historical-data
I don't know if it has resolution sufficient for your needs but I hope so.
Best of luck with your analysis!
Best regards,
Ben
