Request Parameters

1. BLOCK PARAMETER - An int block number in the form of hex, appended with 0x such as 0x6D7FE0, or pre-defined strings latest, earliest, pending.

2. TRANSACTION CALL OBJECT - A transaction object to be broadcasted.

Web3API's Composer accepts int block numbers, which will be auto-converted to a hex representation before being sent to a node.

Within the transaction call object, the following information are required.

1. from: 20 Bytes - address of the sender.

2. to: 20 Bytes - address of the receiver.

3. gas: Hex representation of an integer of the gas provided for the transaction execution. eth_call consumes zero gas, but this parameter may be needed by some executions.

4. gasPrice: Hex representation of an integer of the gasPrice used for each paid gas

5. value: Hex representation of an integer of the value sent with this transaction

6. data: Hash of the method signature and encoded parameters. For details see Ethereum Contract ABI.
