Serialisation

scala> Json.toJson(AiResponse(body = Android(name = "android", version = "1.0")))
res1: play.api.libs.json.JsValue = {"body":{"name":"android","version":"1.0"}}

Deserialisation

scala> Json.fromJson[AiResponse[Android]](Json.parse("""{"body":{"name":"android","version":"1.0"}}"""))
res3: play.api.libs.json.JsResult[AiResponse[Android]] = JsSuccess(AiResponse(Android(android,1.0)),)
