# gettxout - Zcash

This method returns information about a specific transparent unspent transaction output (UTXO). Returns `null` if the output has already been spent or doesn't exist. Note that this method covers **transparent outputs only** — shielded outputs are private by design and cannot be enumerated via this RPC.

## Parameters

| Parameter         | Type    | Required | Description                                                           |
| ----------------- | ------- | -------- | --------------------------------------------------------------------- |
| `txid`            | string  | Yes      | Transaction ID containing the output                                  |
| `n`               | integer | Yes      | Output index (0-based) within the transaction                         |
| `include_mempool` | boolean | No       | If `true`, include mempool transactions in the lookup. Default `true` |

## Use Cases

* **Wallet UTXO Verification**: Confirm a UTXO is still unspent before using it as an input
* **Explorer UTXO Detail**: Show output-level detail on transaction detail pages
* **Balance Reconstruction**: Iterate known UTXOs to reconstruct a wallet's transparent balance
* **Coinbase Maturity Checks**: Detect coinbase UTXOs and enforce the 100-confirmation maturity rule before spending
