Downloading a File
curl --request POST \
  --url https://api.sutro.sh/download-from-dataset \
  --header 'Authorization: <authorization>' \
  --header 'Content-Type: application/json' \
  --data '{
  "dataset_id": "<string>",
  "file_name": "<string>"
}'
{
  "error": "File not found in dataset"
}
Using the API directly is not recommended for most users. Instead, we recommend using the Python SDK.
Download a file from a dataset.

​
Usage Notes

  • You can only download one file at a time via the API. You must make multiple requests to download multiple files. The Python SDK supports downloading multiple files at once.
  • The file will be returned as bytes. You will need to decode the bytes and save them to a file.
  • The dataset stores files in the order they were uploaded. You can view the ordering of files using the list-dataset-files endpoint.

​
Request Body

​
dataset_id
string
required
The ID of the dataset to download the file from
​
file_name
string
required
The name of the file to download

​
Headers

​
Authorization
string
required
Your Sutro API key using Key authentication scheme.Format: Key YOUR_API_KEYExample: Authorization: Key sk_live_abc123...

​
Response

If successful, returns the file as bytes. Otherwise, returns a JSON object containing an error message. 
{
  "error": "File not found in dataset"
}

​
Code Examples

import requests

response = requests.post(
    'https://api.sutro.sh/download-from-dataset',
    headers={
        'Authorization': 'Key YOUR_SUTRO_API_KEY',
        'Content-Type': 'application/json'
    },
    json={
        'dataset_id': 'dataset_12345',
        'file_name': 'data.parquet'
    }
)

# Check if the response is successful and contains file data
if response.headers.get('content-type') == 'application/octet-stream':
    # Save the file bytes to disk
    with open('downloaded_data.parquet', 'wb') as f:
        f.write(response.content)
    print("File downloaded successfully")
else:
    # Handle error response
    error_info = response.json()
    print(f"Download failed: {error_info.get('error', 'Unknown error')}")

​
Response Handling

The API returns different content types based on the result:
  • Successful Download: Content-Type: application/octet-stream with file bytes in the response body
  • Error: Content-Type: application/json with error details
Always check the Content-Type header to determine how to handle the response.

​
Important Considerations

  • Single File Limit: API supports one file per request (use Python SDK for batch downloads)
  • Binary Data: Files are returned as raw bytes that need to be saved to disk
  • File Ordering: Use the list-dataset-files endpoint to see available files and their order
  • Error Handling: Check response headers to distinguish between file data and error messages
