# get\_outs - Monero

This non-JSON-RPC endpoint returns transaction outputs by their global output index. Wallets use this to fetch decoys when constructing ring signatures.

## Parameters

| Parameter | Type    | Required | Description                                           |
| --------- | ------- | -------- | ----------------------------------------------------- |
| outputs   | array   | Yes      | Array of `{amount, index}` pairs to look up           |
| get\_txid | boolean | No       | If `true`, also return the originating transaction ID |

## Request Example
