JSON-RPC

Overview
The Radix Node API uses the JSON-RPC 2.0 specification to encode its messages. The following subsections describe the contents of the JSON messages that follow this spec.
For further reference check the official JSON-RPC 2.0 specification.
Request
An RPC call is represented by sending a request message to the node. The request message has the following members:
id: A unique identifier established by the client that contains a string or number. The server must reply with the same value in the response message. This member is used to correlate the context between both messages.
method: A string containing the name of the method to be invoked.
params: A structured value that holds the parameter values to be used during the invocation of the method.
You can find request examples for each API method in the next section.
Successful response
When an RPC call is made, the server replies with a response message. In case of a successful response, the response message will contain the following members:
jsonrpc: A string specifying the version of the JSON-RPC protocol. It must be 2.0.
id: Must match the value of the id member in the request message.
result: Its value is determined by the method invoked on the server.
You can find successful response examples in the API methods section.
Error response
When an RPC call is made, the server replies with a response message. In case of an error response, the response message will contain the following members:
jsonrpc: A string specifying the version of the JSON-RPC protocol. It must be 2.0.
id: Must match the value of the id member in the request message. If there was an error in detecting the id in the request message (e.g. Parse Error/Invalid Request), id is null.
error: A message describing the error through the following members:
code: An integer number that indicates the error type that occurred.
message: A string providing a short description of the error.
The following example shows a typical error response:
{
    "error": {
        "code": -32601,
        "message": "Method not found"
    },
    "id": 0,
    "jsonrpc": "2.0"
}
