## Client.getAddress().outputs(str)

This
[`Client.getAddress().outputs(str)`](./../libraries/wasm/api_reference#getaddressbuilderoutputsaddress-options--promiseany)
expects an address in Bech32 format and returns a `str[]` of `output_ids`.

<CodeBlock className="language-javascript">{a_get_address_outputs}</CodeBlock>

**Output example**:

```json
[
  "0f2d5d2651f8061a9f5417d0658009f32b2e3f77f9706b0be3b4b3f466171f360000",

]
```

## Client.getOutput(str)

The function [`Client.getOutput(str)`](./../libraries/wasm/api_reference#clientgetoutputoutput_id--promiseany) can be
used to get metadata about the given `output_id`:

<CodeBlock className="language-javascript">{b_get_output}</CodeBlock>

**Output example**:

```json
{
  "messageId": "f303bc90a5ed3ef15af5fc6aa81a739978c59458a71e68ce8e380f1f534da1e6",
  "transactionId": "0f2d5d2651f8061a9f5417d0658009f32b2e3f77f9706b0be3b4b3f466171f36",

  "isSpent": false,

  "amount": 1000000
}
```

## Client.findOutputs(output_ids (optional), addresses (optional))

The function [`Client.findOutputs()`](./../libraries/wasm/api_reference#clientfindoutputsoutputs-addresses--promiseany)
is a convenient shortcut combining both `Client.getAddressOutputs(str)` and `Client.getOutput(str)` methods in a single
call. It supports two arguments, a list of `output_ids` or a list of `addresses`.

<CodeBlock className="language-javascript">{c_find_outputs}</CodeBlock>

**Output example**:

```json
[
  {
    "messageId": "f303bc90a5ed3ef15af5fc6aa81a739978c59458a71e68ce8e380f1f534da1e6",
    "transactionId": "0f2d5d2651f8061a9f5417d0658009f32b2e3f77f9706b0be3b4b3f466171f36",

    "isSpent": false,
    "address": "atoi1qzt0nhsf38nh6rs4p6zs5knqp6psgha9wsv74uajqgjmwc75ugupx3y7x0r",

  },

  }
]
```

- `messageId`: Refers to the encapsulating message in which the transaction was sent.
- `transactionId`, `outputIndex`: Refers to the output within the `SignedTransaction` payload. There may be several
  `outputs` involved in a single transaction, so the `transactionId` by itself would not be enough.
- `output`: This section provides details about the iota address to which the given
  [unspent transaction output](#unspent-transaction-output-utxo) is coupled with.
- `amount`: States an amount of tokens related to the `output`.
- `isSpent`: Indicates whether the given `output` is a part of the actual ledger state or not. As mentioned in the
  [Messages, Payloads, and Transactions section](../../../explanations/messages_payloads_and_transactions.md#unspent-transaction-output-utxo),
  if an output was already spent it is not part of the ledger state any more and is replaced by some other `output(s)`
  in the process.

Notice that the `outputId` that was used in a function call to get output details is the same as a combination of the
`transactionId` and `outputIndex`. This way a transaction is tightly coupled with `outputs` since the
`SignedTransaction` payload is a main vehicle to create and spend `outputs`, and everything is encapsulated in a
[message](../../../explanations/messages_payloads_and_transactions.md#messages).
