Bitcoin Mainnet
Sum of satoshis in UTxOs which reside at the specified address or script pubkey.
In addition to confirmed transactions, mempool endpoints return data which reflects pending transactions in some number of "estimated" blocks - predicted blocks containing transactions which have been propagated around the network but not yet included in a mined block, with transactions with a higher sat/vB value being prioritised. The response details how many of these estimated blocks were considered when fetching the data.
