Once you have installed the add-on on your QuickNode endpoint, then you can start making calls to the qn_translateTransaction passing in a transaction hash as a parameter.

You will then get a response formatted with the original results from the debug_traceTransaction calls along with the translated response. For example, a response for this transaction hash 0x23a9ee5eb6d0bc32c6c499c638c282ffb6448bfd9f957ff50f71ac77ac38ed7b would look like:
