Looking for high-resolution transaction fee (and other) data

Cross-post from the economics forum, I didn't get replies there, and I'm not sure if that's the right place to put this anyway.

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

This is about as good as it gets: https://jochen-hoenicke.de/queue

It provides mempool statistics including transaction volume, fees and mempool size down to 1-minute resolution, and it has data going back to late 2016.

You should note that the data is pulled from Jochen's full node and there is a different setting for the default Core node's mempool. The data should also be considered incomplete, since there is no global mempool. I'm also not sure whether the data is exportable.

Good luck.
