1 credit per API call

Get information about a transaction output in a transaction and check whether this output is a UTXO or has been spent.

"UTXO" stands for "Unspent Transaction Output". A UTXO is the amount of BTC/satoshis that remains at a Bitcoin address after a cryptocurrency transaction involving this address has been performed. The UTXO can then be used as input for a new cryptocurrency transaction. For more information about Bitcoin transactions and UTXO, see the Bitcoin user documentation.

  • If the transaction output is an UTXO, the API returns data about it.
  • If the transaction output has been spent and there is no UTXO to return, the API returns an error with the 404 response code.
