 The same call can also be invoked from outside the node too via HTTP RPC (e.g. using Curl). In this case, the HTTP endpoint must be enabled in Geth using the `--http` command and the `debug` API namespace must be exposed using `--http.api=debug`.

 To follow along with this tutorial, transaction hashes can be found from a local Geth node (e.g. by attaching a [Javascript console](/docs/interacting-with-geth/javascript-console) and running `eth.getBlock('latest')` then passing a transaction hash from the returned block to `debug.traceTransaction()`) or from a block explorer (for [Mainnet](https://etherscan.io/) or a [testnet](https://goerli.etherscan.io/)).
