Request Parameters

• txid (string, required): The transaction ID.
• vout (numeric, required): The output number.
• sequence (numeric, optional): The sequence number, default value depends on the 'replaceable' and 'locktime' arguments.
• address (numeric or string, required): A key-value pair where the key is the Bitcoin address and the value is the amount in BTC.
• data (string, required): A key-value pair where the key must be "data" and the value is hex-encoded data.
• locktime (raw, optional): Non-0 value also locktime-activates inputs.
• replaceable (boolean, optional): Marks this transaction as BIP125-replaceable. Allows this transaction to be replaced by a transaction with higher fees

Response

{
  "result": "hex-encoded raw transaction",
  "error": null,
  "id": "coinapi_test"
}
