NOWNodes API key passed in the api-key header.

Modified in Groestlcoin Core 31.0.0 > 32.1.0:

Adds vsize_adjusted (policy/sigop-adjusted) and vsize_bip141 (raw BIP141 virtual size); legacy vsize is deprecated and represents adjusted size.
The bip125-replaceable response field is omitted by default; available only with node startup flag -deprecatedrpc=bip125.

Returns all transaction IDs currently in the mempool. If verbose is true, returns a JSON object with detailed mempool entry information for each transaction.
