# Get Dataset

GET https://api.humanloop.com/v5/datasets/{id}

Retrieve the Dataset with the given ID.

Unless `include_datapoints` is set to `true`, the response will not include
the Datapoints.
Use the List Datapoints endpoint (`GET /{id}/datapoints`) to efficiently
retrieve Datapoints for a large Dataset.

By default, the deployed version of the Dataset is returned. Use the query parameters
`version_id` or `environment` to target a specific version of the Dataset.

Reference: https://humanloop.com/docs/api/datasets/get

## Authentication

- `X-API-KEY` header (required) — API Key authentication via header

## Request

### Path parameters

- `id` (string, required) — Unique identifier for Dataset.

### Query parameters

- `version_id` (string, optional) — A specific Version ID of the Dataset to retrieve.
- `environment` (string, optional) — Name of the Environment to retrieve a deployed Version from.
- `include_datapoints` (boolean, optional, default: false) — If set to `true`, include all Datapoints in the response. Defaults to `false`. Consider using the paginated List Datapoints endpoint instead.

## Response

Successful Response

- `path` (string, required) — Path of the Dataset, including the name, which is used as a unique identifier.
- `id` (string, required) — Unique identifier for the Dataset. Starts with `ds_`.
- `name` (string, required) — Name of the Dataset, which is used as a unique identifier.
- `version_id` (string, required) — Unique identifier for the specific Dataset Version. If no query params provided, the default deployed Dataset Version is returned. Starts with `dsv_`.
- `created_at` (datetime, required)
- `updated_at` (datetime, required)
- `last_used_at` (datetime, required)
- `datapoints_count` (integer, required) — The number of Datapoints in this Dataset version.

- `environments` (list of EnvironmentResponse, optional) — The list of environments the Dataset Version is deployed to.
- `created_by` (any, optional) — The user who created the Dataset.
- `version_name` (string, optional) — Unique name for the Dataset version. Version names must be unique for a given Dataset.
- `version_description` (string, optional) — Description of the version, e.g., the changes made in this version.
- `datapoints` (list of DatapointResponse, optional) — The list of Datapoints in this Dataset version. Only provided if explicitly requested.
- `attributes` (map from string to any, optional) — Additional fields to describe the Dataset. Helpful to separate Dataset versions from each other with details on how they were created or used.
