Path Parameters
An address, an extended public key, or an output descriptor. Supported descriptor form: pkh(...). Must be an account-level key, not a master key. URL-encode the descriptor when placing it in the REST path.
Descriptors containing a / are not supported and return an error.
This includes:
- key origin prefixes:
pkh([73c5da0a/44'/133'/0']xpub...) - multipath selectors:
pkh(xpub.../<0;1>/*) - explicit branch paths:
pkh(xpub.../0/*)
Percent-encoding the slash does not help. Note the origin prefix cannot be shortened either, since it contains slashes of its own.
Use the bare form instead - pkh(xpub...) - which is fully supported. The branch selector is unnecessary: Blockbook automatically scans both the receive (0) and change (1) branches for the account.
Query Parameters
When set to true, only returns confirmed UTXOs. When false or omitted, returns both confirmed and unconfirmed.
The gap limit used when deriving addresses from an extended public key (xpub). Defaults to 20.
Returns
Transaction ID of the UTXO
Output index in the transaction
UTXO value in satoshis
Block height where the UTXO was created
Number of confirmations
The address this UTXO belongs to. Returned only for xpub and descriptor queries; omitted for single-address queries.
BIP32 derivation path of the address, e.g. m/44'/133'/0'/0/0. The last two segments are the branch (0 = receive, 1 = change) and the address index. Returned only for xpub and descriptor queries; omitted for single-address queries.
