Is it possible to check somehow the group of params? E.g.: I have three query params on input: one, two, three, and I want to check if one of them is present. Im using schema validation.

It looks like a problem because schemas are referencing always to the specific fields :~

    'limit': {
        optional: true,
        isInt: {
            errorMessage: 'Invalid argument type.'
        }
    },
    'offset': {
        optional: true,
        isInt: {
            errorMessage: 'Invalid argument type.'
        }
    }

Is there an option to check several fields of request, the whole request? For example, my api receive a request from transfer money tool, which has parameters:

{
   "fromAccount":"100001",
   "toAccount":"100001",
   "amount":2344.23,
}

So we validated each parameter in separate way, but we also need to check that fromAccount !== toAccount somehow.

@agauniyal you can already do this. These 3 fields are always required, and make the 4th one optional. If one of these 3 fields are not sent, then the request should fail.
