# List Files

`files.list(**kwargs) -> PageCursor<FileMetadata>`

**GET** `/v1/files`

List Files

## Parameters

- `ids: Array[String]` (query parameter)

  Restrict the result set to Files whose `id` is in this list. At most 100 entries (after de-duplication). Mutually exclusive with `page` and `limit`. When supplied, the response is always a single page (`next_page` is null). IDs that do not resolve to a visible File — including deleted Files — are silently omitted.

- `limit: Integer` (query parameter)

  Number of items to return per page.

  Defaults to `20`. Ranges from `1` to `1000`.

  minimum: 1, maximum: 1000

- `page: String` (query parameter)

  Opaque page cursor returned in a prior list response's `next_page`. Prefixed `page_`.

- `workspace_id: String` (header parameter)

  Optional header to select the Workspace for this request. The value is a Workspace ID (for example, `wrkspc_011CZkZaBF1tNoB5wlCeusgy`).

  Only needed for credentials that can act on more than one Workspace. A credential that belongs to a specific Workspace may omit it; if sent, it must match that Workspace.

## Returns

- `class FileMetadata`

  - `type: :file`

    Object type.

    For files, this is always `"file"`.

  - `id: String`

    Unique object identifier.

    The format and length of IDs may change over time.

  - `created_at: Time`

    RFC 3339 datetime string representing when the file was created.

    format: date-time

  - `filename: String`

    Original filename of the uploaded file.

    minLength: 1, maxLength: 500

  - `mime_type: String`

    MIME type of the file.

    minLength: 1, maxLength: 255

  - `size_bytes: Integer`

    Size of the file in bytes.

    minimum: 0

  - `downloadable: bool`

    Whether the file can be downloaded.

  - `expires_at: Time`

    RFC 3339 datetime string representing when the file will expire and become unavailable for download. Null if the file does not expire. For files uploaded with `expires_in_seconds`, this is the upload time plus that value.

    format: date-time

## Example

```ruby
require "anthropic"

anthropic = Anthropic::Client.new(api_key: "my-anthropic-api-key")

page = anthropic.files.list

puts(page)
```
