Here's another alternative:

{
    "methodCall": {
        "methodName": "examples.echoParams",
        "params": [
            {"#type:dateTime": "2018-06-10T19:41:06.199Z"},
            {"#type:base64": "aGVsbG8gd29ybGQ="}
        ]
    }
}

got the idea of encoding the type in the property name from: https://www.tjson.org/
