Use the S3-compatible API

E2E Object Storage supports any S3-compatible SDK; E2E recommends a MinIO SDK for the smoothest experience. The examples use Python. You need a bucket and an access key first; see Generate an access key.

Install the SDK and connect

pip install minio

from minio import Minio

client = Minio(
    "objectstore.e2enetworks.net",  # Delhi; use "in-south1-objectstore.e2enetworks.net" for a Chennai bucket
    access_key="<access-key>",
    secret_key="<secret-key>",
    secure=True,
)

List, upload, and download objects

# List objects in a bucket
for obj in client.list_objects("<bucket-name>", recursive=True):
    print(obj.object_name, obj.size)

# Upload a file
client.fput_object("<bucket-name>", "<object-name>", "<local-file-path>")

# Download a file
client.fget_object("<bucket-name>", "<object-name>", "<local-file-path>")

# Download only a byte range of a file, instead of the whole object
client.get_object("<bucket-name>", "<object-name>", offset=<start-byte>, length=<byte-count>)

Run the list loop first to check the connection. It prints each object’s name and its size in bytes, one per line:

report.pdf 1258291
logs/app-2026-09-22.gz 48213

Nothing printed means the bucket is empty; an access error means the key has no role on it.

Remove an object

client.remove_object("<bucket-name>", "<object-name>")

Remove every object under a prefix in one call instead of one at a time:

names = (obj.object_name for obj in client.list_objects("<bucket-name>", prefix="<prefix>", recursive=True))
for error in client.remove_objects("<bucket-name>", names):
    print("Deletion error:", error)

Generate a presigned URL in code

from datetime import timedelta

url = client.presigned_get_object("<bucket-name>", "<object-name>", expires=timedelta(days=<days>))

The SDK has an equivalent call for an upload link instead of a download one; see Share an object with a presigned URL for the same thing from the dashboard, and the expiry limit that applies either way.

Supported operations

E2E Object Storage supports these object-level operations, the everyday work an S3-compatible SDK does. For bucket-level work, see Creating and listing buckets.

Operation	What it does
list_objects	List the objects in a bucket
get_object	Download an object
remove_object	Delete an object
put_object	Upload an object
copy_object	Copy an object within a bucket
remove_objects	Delete several objects at once
fput_object	Upload a file as an object
fget_object	Download an object to a file
get_partial_object	Download a byte range of an object
select_object_content	Query an object’s contents with an SQL-like statement
remove_incomplete_upload	Remove a multipart upload that never finished
presigned_get_object	Make a presigned download URL
presigned_put_object	Make a presigned upload URL

The MinIO SDKs expose each of these as a method; the code in List, upload, and download objects uses a few of them.

Creating and listing buckets

An SDK with an access key works on the objects in the buckets that key is attached to. To create a bucket or list every bucket on your account, use the dashboard, or the MyAccount API with your account API key, which is separate from an access key. See S3 compatibility for the complete list of what carries over from S3 and what does not.

If a call fails with an access error, check the key’s role on that bucket in Generate an access key, or see Troubleshooting E2E Object Storage.
