We can check the config of any running bundler. A sample request through curl like this can be used, with any Skandha bundler deployment being the endpoint. This can be run in any command line. skandha_config is the method. 
curl --location 'https://rpc.etherspot.io/v1/137' \
--header 'Content-Type: application/json' \
--data '{
    "id": 3,
    "method": "skandha_config",
    "jsonrpc": "2.0"
}'
A successful response will look like this: 
{
    {
        "jsonrpc":"2.0",
        "id":3,
        "result": {
