DRF: get allowed filters

I'va a django-rest-framework viewset like this:

class MyFilterSet(django_filters.FilterSet): 

    class Meta:
        model = MyModel

    fields = {
        'code': ['exact', 'icontains', 'istartswith'],
        'name': ['exact', 'icontains', 'istartswith'],
        'status': ['exact'],
        ...
    }


class MyViewSet(viewsets.ModelViewSet):

    serializer_class = MySerializer
    model = MyModel

    filter_backends = (filters.OrderingFilter, filters.SearchFilter, filters.DjangoFilterBackend)

    # for DjangoFilterBackend
    filter_class = MyFilterSet

    # for SearchFilter
    search_fields = (
        'code',
        'name',
        'description',
        ...
    )

    # for OrderingFilter
    ordering_fields = ('code', 'name', 'status', ...)

How can I inspect this API to get allowed filters (needed by my frontend page)?
