Remote Procedure Call (RPC)

RPC API Reference

By default, RPC API listens on 20336 port.

The following option can be used to change the port at which the client side RPC API listens:

ontology --rpcport 1024

The following option can be used to stop the client side RPC service:

ontology --disable-rpc

Remote Procedure Call (RPC), also known as function call or subroutine call, are used on one machine on a network to request services from another machine without the need of detailed network information.

Interface definition

The JSON-RPC interface definition is as follows:

Response parameters

Field	Description
TxHash	Transaction hash
State	Transaction execution status, 0 indicates execution failure, 1 indicates execution success
GasConsumed	Amount of gas consumed for execution
Notify	Contract events triggered by the transaction

The two fields within Notify:

Field	Description
ContractAddress	Contract address where the event occurred
States	Event details

When the block height is passed as the parameter, the response contains the list of all the transactions that are the execution result.

When a transaction hash is passed as the parameter, the response contains the execution result of the particular transaction.

The States field specified in the Notify field is a hex string in for single transactions, and an array for multiple transactions.
