`summarize` _boolean_ Default: `false`

Text Intelligence English (all available regions)

Summarization accepts an input text and analyzes the text. It then summarizes the content of the submitted text and returns a brief summary in the JSON response.

```json
 "results": {
    "summary": {
      "text": "Jake calls the Honda dealership and speaks with Josh about the new Honda Civic 2023. Jake schedules a test drive for the hybrid model on Friday and provides his contact information.Josh confirms the appointment and tells Jake to call if he has any further questions."
    }
  }
```

## Enable Feature

To enable Summarization, use the following parameter in the query string when you call Deepgram’s `/read` endpoint :

`summarize=true`

### Basic Text Request

To analyze text from a file on your computer, run the following curl command in a terminal or your favorite API client.

```bash
 curl -vX POST \
	-H "Authorization: Token YOUR_DEEPGRAM_API_KEY" \
	-H "Content-Type: application/json" \
	-d '{"text": "YOUR_TEXT_HERE"}' \
	"https://api.deepgram.com/v1/read?summarize=true&language=en"
```

:::callout{intent="warning"}
Replace `YOUR_DEEPGRAM_API_KEY` with your [Deepgram API Key](https://console.deepgram.com/signup?jump=keys).
:::

### Basic URL Request

To analyze text from a hosted file, run the following curl command in a terminal or your favorite API client. (Try testing it out with the hosted file https://static.deepgram.com/examples/aura.txt)

```bash
curl -vX POST \
 -H "Authorization: Token YOUR_DEEPGRAM_API_KEY" \
 -H "Content-Type: application/json" \
 -d '{"url": "https://YOUR_FILE_URL.txt"}' \
 "https://api.deepgram.com/v1/read?summarize=true&language=en"
```

### Query Parameters

| Parameter   | Value  | Type    | Description                                                                                                                                                                   |
| ----------- | ------ | ------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `summarize` | `true` | boolean | Enables summarization. The output response will include a `summary` object, and within that object will be a `text`property that contains a short summary of the entire text. |
| `language`  | `en`   | string  | The language of your input text (Only English is supported at this time)                                                                                                      |

:::callout{intent="info"}
Summarization requires a minimum of greater than 50 words for summarization. For shorter inputs (less than 50 words), the original input will be returned. In this case, no tokens in or out are billed as summarization usage.
:::

## Analyze Response

When the file is finished processing, you’ll receive a JSON response that has the following basic structure:

```json
{
  "metadata": {
    "request_id": "6ab1afe9-da49-4688-86f5-ae2fde420ad4",
    "created": "2023-11-28T04:49:56.034Z",
    "language": "en",
    "summary_info": {
      "model_uuid": "67875a7f-c9c4-48a0-aa55-5bdb8a91c34a",
      "input_tokens": 103,
      "output_tokens": 33
    }
  },
  "results": {
    "summary": {
      "text": "Jake calls the Honda dealership and speaks with Josh about the new Honda Civic 2023. Jake schedules a test drive for the hybrid model on Friday and provides his contact information. Josh confirms the appointment and tells Jake to call if he has any further questions."
    }
  }
}
```

The `summary` object contains:

- `text`: Short summary of the audio being summarized.
