# OptionsObjectCORS

Available in Classic and VPC

By sending an OPTIONS request with the path to the object along with the origin and request type, you can check whether the object is accessible from the origin with that request type.

## Requests

The following describes the request format for the endpoint. The request format is as follows.

| Method | URI |
| --- | --- |
| OPTIONS | /{bucket-name}/{object-name} |

### Request syntax

The request syntax is as follows.

```
OPTIONS https://{endpoint}/{bucket-name}/{object-name} # path style
OPTIONS https://{bucket-name}.{endpoint}/{object-name} # virtual host style
```

### Request headers

For headers common to all Object Storage APIs, see [Object Storage common headers](/docs/en/storage-objectstorage#%EA%B3%B5%ED%86%B5-%EC%9A%94%EC%B2%AD-%ED%97%A4%EB%8D%94).

              Note

              

If the method is OPTIONS, the `Authorization` header and `x-amz-date` header are not required.

| Field | Type | Required | Description |
| --- | --- | --- | --- |
| `bucket-name` | String | Required | Name of the bucket where the object is stored |
