# Code Samples

> Curl-based examples for common Rosetta API operations

Canonical URL: https://docs.minaprotocol.com/node-operators/rosetta/samples/

These samples use `curl` and [`jq`](https://jqlang.github.io/jq/) to interact with the Rosetta API. They assume a running Rosetta instance on `localhost:3087`.

Set these shell variables before running the examples:

```bash
ROSETTA_URL="http://localhost:3087"
NETWORK='{"blockchain":"mina","network":"mainnet"}'
```

All endpoints except `/network/list` require a `network_identifier` parameter. The samples include it in each request body.

:::tip
Replace `mainnet` with `devnet` if you are testing against a devnet instance.
