Response body:

{"jsonrpc": "id": 1, "result": {"txid": "0xff488264c1abf9f5c3c17ed8071f6dd3cd809b25797a43af49316490ded8fb07", "executions": [{"trigger": "Application", "contract": "0x0110a8f666bcc650dc0b544e71c31491b061c79e", "vmstate": "HALT, BREAK" "gas_consumed": "2.855", "stack": [{"type": "Integer", "value": "1"}] "notifications": [{"contract": "0xb9d7ea3062e6aeeb3e8ad9548220c4ba1361d263", "state": {"type": "Array" "value": [{"type": "ByteArray", "value": "7472616e73666572"} {"type": "ByteArray", "value": "e3069da508f128069a0cd2544b0728ccbacdfb43"}, {"type": "ByteArray" "value": "d142f89e93b2717426a8130c37dad93aad70cff5"}, {"type": "ByteArray" "value": "00e1f50500000000"}]}}

Note: where gas_consumed indicates the number of gas consumed by the transaction, that is, the transaction fee. There will be a free quota of 10 gas for each transaction. If the quantity is less than 10, no handling fee will be charged. If it is greater than 10, then the portion over 10 will be charged as the handling fee and rounded up. For example, if gas_consumed = 12.3, the actual handling fee is 3 gas.
