### Fetch Stealth Transactions in JSON Format with Height Filter

Source: https://github.com/libbitcoin/libbitcoin-explorer/wiki/bx-fetch-stealth

Retrieves stealth transaction metadata in JSON format, filtering transactions from a minimum block height. This example uses a short prefix '01'.

```sh
$ bx fetch-stealth -f json -t 325500 01
```

```json
