Is this a valid listMarketProfitAndLoss call?

[{"jsonrpc": "2.0", "method": "SportsAPING/v1.0/listMarketProfitAndLoss","params": {"marketId": "1.112809424"}, "id": 1}]

I keep getting this returned...

[{"jsonrpc":"2.0","error":{"code":-32602,"message":"DSC-0018"},"id":1}]

The visualiser should give a JSON output string so that we know how to code it. The API reference may as well be in Demotic Egyptian for all the good it is. At least, there should be an example for each operation.
