Parity Tracing API methods give users access to the most detailed information about on-chain activity. For more information about use, see the Parity/Open Ethereum Trace API Documentation.
These API methods allow you to get a full externality trace on any transaction executed throughout the Ethereum chain. Unlike the log filtering API, you are able to search and filter based only upon address information. Information returned includes the execution of all CREATE,SUICIDE and all variants of CALL together with input data, output data, gas usage, amount transferred and the success status of each individual action.
