GET https://api.ideogram.ai/datasets/{dataset_id}

Returns a dataset by ID, including the total number of files and a list of each file's name and size in bytes.


Reference: https://developer.ideogram.ai/v1/api-reference/custom-model-training/get-dataset

## Authentication

- `Api-Key` header (required) — API key for access control. Use in the header with the name \"Api-Key\"

## Request

### Path parameters

- `dataset_id` (string, required)

## Response

### 200

Dataset retrieved successfully

- `dataset` (Dataset, required) — A dataset for organizing training images.
- `file_count` (integer, required) — Total number of files in the dataset.
- `files` (list of DatasetFile, required) — List of files in the dataset.
- `custom_model_ids` (list of string, required) — IDs of all custom models trained from this dataset. Empty array if no model has been trained yet.

## Errors

### 401 Unauthorized Error

Unauthorized

- `any`

### 404 Not Found Error

Dataset not found

- `any`

## Types

### Dataset

A dataset for organizing training images.

- `dataset_id` (string, required) — Unique identifier for the dataset.
- `name` (string, required) — Display name of the dataset.
- `user_id` (string, required) — ID of the user who owns this dataset.
- `creation_time` (datetime, required) — When the dataset was created.

### DatasetFile

A file in a dataset.

- `file_name` (string, required, nullable) — Filename of the file in the dataset.
- `file_size_bytes` (integer, optional, nullable) — Size of the file in bytes, if available.
- `caption` (string, optional, nullable) — Caption applied to the file, if any. A v4 structured caption is returned as a JSON-encoded string; a plain-text caption (from a .txt sidecar) is returned unchanged. Only present when the file has a caption.
