Neon is expanding into a backend: Object Storage, Functions, and AI Gateway now in beta
/APIs & SDKs/Buckets/Download an object's bytes
GET/projects/{project_id}/branches/{branch_id}/buckets/{bucket_name}/objects/{object_key}/downloadbeta

Download an object's bytes

Streams the raw bytes of the named object from the bucket on the specified branch, including objects inherited from ancestor branches. Served by the user's session (no customer S3 credentials required).

The body is returned as application/octet-stream so a browser treats it as a download; the Content-Length and ETag response headers echo the stored object metadata.

BINARY-STREAM EXCEPTION TO THE BUILD-GENERATED-TYPES RULE (#7029): the successful 200 body is the raw object stream, proxied verbatim from the platform storage admin endpoint. It is modeled as an application/octet-stream binary body (not a JSON response schema) and is streamed without buffering the whole object in memory. Error responses still use the generated GeneralError shape.

Note: This endpoint is currently in Private Beta.

Markdown for AI context

Quick start

REST API - curl
curl "https://console.neon.tech/api/v2/projects/$PROJECT_ID/branches/$BRANCH_ID/buckets/$BUCKET_NAME/objects/$OBJECT_KEY/download" \
  -H "Authorization: Bearer $NEON_API_KEY"

Every field below is optional. An empty body works too.

Also available in
import { createNeonClient, raw } from '@neon/sdk';

const neon = createNeonClient({ apiKey: process.env.NEON_API_KEY });
const { data } = await raw.getProjectBranchBucketObject({
  client: neon.client,
  path: {
    project_id: process.env.PROJECT_ID,
    branch_id: process.env.BRANCH_ID,
    bucket_name: process.env.BUCKET_NAME,
    object_key: process.env.OBJECT_KEY
  }
});

Parameters

Project ID
project_id
string

The Neon project ID

Branch ID
branch_id
string

The Neon branch ID

Bucket name
bucket_name
string

The bucket name

Object key
object_key
string

The object key. Keys may contain /; the / characters of nested keys must be percent-encoded (%2F) in the path segment.

Response

200

The object's raw bytes, streamed verbatim. Content-Length and ETag headers are set from the stored object metadata; X-Content-Type-Options and Content-Disposition harden the browser against the caller-controlled bytes.

No example available.

Errors

404

Object not found

default

General error

This endpoint can return the standard Neon API error response.

Response fields

  • message Required. Human-readable error message.
  • code Required. Machine-readable error code.
  • request_id Optional. Request identifier for debugging. You can provide one with the X-Request-ID header.

Retry guidance

If no response is returned, the request may still have reached the server. This is why retry safety depends on the method and status code.

Idempotent methods (GET, HEAD, OPTIONS) are generally safe to retry after a network error or timeout. Non-idempotent methods (POST, PATCH, DELETE, PUT) can change state, so avoid automatic retries unless your workflow can tolerate duplicate effects.

Responses with 423 Locked or 503 Service Unavailable are safe to retry. 423 Locked means the resource is temporarily locked, usually because another operation is in progress.
