# Storage

This read-only endpoint returns the S3 connection details for a branch: `s3_endpoint`, `region`, and `force_path_style`. Call it before issuing bucket calls, so you know the branch is ready and you have the endpoint your S3 client needs.

A `404` means object storage isn't available for that branch, with a `reason` field explaining why.

Neon Object Storage uses path-style addressing only, which is why `force_path_style` is returned. See [S3 compatibility](/docs/storage/s3-compatibility) for client configuration and [Buckets](/docs/reference/api/buckets) for the endpoints that read and write data, or manage buckets and objects from the CLI with [`neon buckets`](/docs/cli/buckets), which handles these S3 details for you.

Object Storage is currently available in AWS US East (Ohio), US East (N. Virginia), Europe (Frankfurt), and Asia Pacific (Singapore). Support is expanding toward [all regions](/docs/introduction/regions).

> API Reference / Storage / Get branch object storage state

## GET /projects/{project_id}/branches/{branch_id}/storage

Returns whether branchable object storage is usable for the specified
branch. A 200 response means the branch is registered in the object storage
service and the S3 data plane will accept requests for it. A 404
response includes a `reason` field indicating why object storage is unavailable.

**Note**: This endpoint is currently in Beta.


### Parameters

- `project_id` (string, path, required)
  The Neon project ID
- `branch_id` (string, path, required)
  The Neon branch ID

### Response (200)

```json
{
  "enabled": true,
  "s3_endpoint": "https://br-young-forest-a5b6c7d8.storage.c-5.us-east-2.aws.neon.tech",
  "region": "us-east-2",
  "force_path_style": true
}
```

### Code examples

```bash
curl "https://console.neon.tech/api/v2/projects/$PROJECT_ID/branches/$BRANCH_ID/storage" \
  -H "Authorization: Bearer $NEON_API_KEY"
```

```typescript
import { createNeonClient, raw } from '@neon/sdk';

const neon = createNeonClient({ apiKey: process.env.NEON_API_KEY });
const { data } = await raw.getProjectBranchStorage({
  client: neon.client,
  path: {
    project_id: process.env.PROJECT_ID,
    branch_id: process.env.BRANCH_ID
  }
});
```

### Errors

**404**
Object storage is not enabled for this branch, or the project/branch was not
found. The body is always `BranchStorageNotEnabled` — see `reason` for
the exact cause.

- `code` (string, required)
- `message` (string, required)
- `reason` (string, required)
  Machine-readable reason why object storage is unavailable:
  - `org_not_entitled`: the org's `PlatformBranchableStorage` feature flag is off.
  - `region_unavailable`: the project's region has no object storage admin service wired.
  - `branch_directory_missing`: the branch is not registered in the object storage service.
  - `branch_not_found`: the project or branch does not exist, or the caller does not
    have access to it.
  
  Possible values: `org_not_entitled`, `region_unavailable`, `branch_directory_missing`, `branch_not_found`

**default**
General Error.

The request may or may not be safe to retry, depending on the HTTP method, response status code,
and whether a response was received.

- If no response is returned from the API, a network error or timeout likely occurred.
- In some cases, the request may have reached the server and been successfully processed, but the response failed to reach the client. As a result, retrying non-idempotent requests can lead to unintended results.

The following HTTP methods are considered non-idempotent: `POST`, `PATCH`, `DELETE`, and `PUT`. Retrying these methods is generally **not safe**.
The following methods are considered idempotent: `GET`, `HEAD`, and `OPTIONS`. Retrying these methods is **safe** in the event of a network error or timeout.

Any request that returns a `503 Service Unavailable` response is always safe to retry.

Any request that returns a `423 Locked` response is safe to retry. `423 Locked` indicates that the resource is temporarily locked, for example, due to another operation in progress.

- `request_id` (string, optional)
  Unique identifier for the request, useful for debugging.
  You can set this value manually by including an `X-Request-ID` header in the request. If not provided, the value will be generated automatically.
  
- `code` (string, required)
  Machine-readable code classifying the error type. See `message` for a human-readable explanation.
  Default: ``
- `message` (string, required)
  Error message
