Get utxo

Returns array of unspent transaction outputs of address or xpub, applicable only for Bitcoin-type coins. By default, the list contains both confirmed and unconfirmed transactions. The query parameter confirmed=true disables return of unconfirmed transactions. The returned utxos are sorted by block height, newest blocks first. For xpubs or output descriptors, the response also contains address and derivation path of the utxo.

Unconfirmed utxos do not have field height, the field confirmations has value 0 and may contain field lockTime, if not zero.

Coinbase utxos have field coinbase set to true, however due to performance reasons only up to minimum coinbase confirmations limit (100). After this limit, utxos are not detected as coinbase.
