Some kind of implementation is needed. Currently we just return [[0, 0]]

As short as possible really. I need help in figuring out how to implement this.

Perhaps this can also be implemented using the https://mempool.space API?

i'm not sure that the libbitcoin-server api supports what is needed for this. given a tx identifier, we can obtain fee data from the mem/transaction pool. but I don't see a way to get an index of all tx in the pool. the bitcoin core rpc has a method 'getrawmempool' that will return such a list. i believe this is what electrumx is using. am i missing something?

Hi. I've asked about this in https://github.com/libbitcoin/libbitcoin-server/issues/547

I think you're indeed right, and this functionality may be missing. However, it should be possible to implement it.
