### Path Parameters

- `account_id: string`

  Account ID.

  Name of the bucket.

### Header Parameters

- `"cf-r2-jurisdiction": optional "default" or "eu" or "fedramp"`

  Jurisdiction where objects in this bucket are guaranteed to be stored.

  - `"default"`

  - `"eu"`

  - `"fedramp"`

### Returns

- `errors: array of ResponseInfo`

  - `code: number`

  - `message: string`

  - `documentation_url: optional string`

  - `source: optional object { pointer }`

    - `pointer: optional string`

- `messages: array of string`

- `result: object { rules }`

  - `rules: optional array of object { allowed, id, exposeHeaders, maxAgeSeconds }`

    - `allowed: object { methods, origins, headers }`

      Object specifying allowed origins, methods and headers for this CORS rule.

      - `methods: array of "GET" or "PUT" or "POST" or 2 more`

        Specifies the value for the Access-Control-Allow-Methods header R2 sets when requesting objects in a bucket from a browser.

        - `"GET"`

        - `"PUT"`

        - `"POST"`

        - `"DELETE"`

        - `"HEAD"`

      - `origins: array of string`

        Specifies the value for the Access-Control-Allow-Origin header R2 sets when requesting objects in a bucket from a browser.

      - `headers: optional array of string`

        Specifies the value for the Access-Control-Allow-Headers header R2 sets when requesting objects in this bucket from a browser. Cross-origin requests that include custom headers (e.g. x-user-id) should specify these headers as AllowedHeaders.

    - `id: optional string`

      Identifier for this rule.

    - `exposeHeaders: optional array of string`

      Specifies the headers that can be exposed back, and accessed by, the JavaScript making the cross-origin request. If you need to access headers beyond the safelisted response headers, such as Content-Encoding or cf-cache-status, you must specify it here.

    - `maxAgeSeconds: optional number`

      Specifies the amount of time (in seconds) browsers are allowed to cache CORS preflight responses. Browsers may limit this to 2 hours or less, even if the maximum value (86400) is specified.

  Whether the API call was successful.

  - `true`
