Basically I’m looking for the number of blocks in the mempool, secondary metric would be number of transactions.

In this case, it would include the data from the left most block in the pic and all other blocks to the right that have yet to be mined.

I’ll look at the API docs in a bit. Also nostr:npub1uvl7vhclmezvdhqha6eclkksln40rjhgwgsggvew683jf93fr4pq3mq3sd might be able to tell us how to get this info easily
