--- title: Files url: https://platform.claude.com/docs/en/api/python/files --- # Files ## Upload File `files.upload(**kwargs) -> FileMetadata` **POST** `/v1/files` Upload File ### Parameters - `file: FileTypes` The file to upload. Only the final path component of the part's `filename` is kept; an absent or empty `filename` is replaced with `unnamed` plus the extension for the file's stored `mime_type`, when known. format: binary - `expires_in_seconds: Optional[int]` Seconds from upload until the file expires and its bytes become permanently unavailable. Must be between 3600 (one hour) and 7776000 (ninety days). minimum: 3600, maximum: 7776000 - `workspace_id: Optional[str]` (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: Literal["file"]` Object type. For files, this is always `"file"`. - `id: str` Unique object identifier. The format and length of IDs may change over time. - `created_at: datetime` RFC 3339 datetime string representing when the file was created. format: date-time - `filename: str` Original filename of the uploaded file. minLength: 1, maxLength: 500 - `mime_type: str` MIME type of the file. minLength: 1, maxLength: 255 - `size_bytes: int` Size of the file in bytes. minimum: 0 - `downloadable: Optional[bool]` Whether the file can be downloaded. default: false - `expires_at: Optional[datetime]` 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 ```python import os from anthropic import Anthropic client = Anthropic( api_key=os.environ.get( "ANTHROPIC_API_KEY" ), # This is the default and can be omitted ) file_metadata = client.files.upload( file=b"Example data", ) print(file_metadata.id) ``` #### Response (200) ```json { "id": "file_011CNha8iCJcU1wXNR6q4V8w", "created_at": "2025-04-15T18:37:24.100435Z", "filename": "document.pdf", "mime_type": "application/pdf", "size_bytes": 102400, "type": "file", "downloadable": false, "expires_at": "2025-05-15T18:37:24.100435Z" } ``` ## List Files `files.list(**kwargs) -> SyncPageCursor[FileMetadata]` **GET** `/v1/files` List Files ### Parameters - `ids: Optional[Sequence[str]]` (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: Optional[int]` (query parameter) Number of items to return per page. Defaults to `20`. Ranges from `1` to `1000`. default: 20, minimum: 1, maximum: 1000 - `page: Optional[str]` (query parameter) Opaque page cursor returned in a prior list response's `next_page`. Prefixed `page_`. - `workspace_id: Optional[str]` (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.
