# Series by ID

> Retrieve a single Polymarket series with optional chat data via gamma.series.getSeriesById.

`client.gamma.series.getSeriesById` fetches a specific series, including nested events, chat details,
and tags.

## Request

```ts theme={null}
const [series] = await client.gamma.series.getSeriesById(id, params);
```

### Parameters

| Name           | Type           | Required | Notes                  |
| -------------- | -------------- | -------- | ---------------------- |
| `id`           | `number` (≥ 0) | ✅        | Series ID.             |
| `include_chat` | `boolean`      |          | Include chat metadata. |

## Response

An array containing one `Series` object (consistent with the upstream API). Fields match the
structure returned by [`List Series`](/gamma/series-list).

## Usage example

```ts theme={null}
const [series] = await client.gamma.series.getSeriesById(10388, { include_chat: true });

console.log(series.title);
```

## Failure modes

* `id` must be numeric.
