Get file metadata

GET /v1/compliance/apps/chats/files/\{claude_file_id\}

Retrieves metadata for a file referenced in chat messages, without downloading the file content. Use the sibling /content endpoint to download the bytes.

Path parameters

• claude_file_id: string

  The file ID (tagged ID, e.g., claude_file_abc123)

Headers

• "anthropic-version": optional string

  The version of the Claude API you want to use.

  Read more about versioning and our version history here.

• "x-api-key": optional string

Returns

• id: string

  File ID

• claude_chat_ids: array of string

  Chats this file is attached to. A file can be referenced by messages across multiple chats.

• created_at: string

  File creation timestamp

  format: date-time

• filename: string or null

  Display name of the file, if set

• md5: string or null

  Lowercase hex MD5 of the file's preferred downloadable variant, as recorded at upload time. Null when no stored hash is available. The sibling /content endpoint also sets a Content-MD5 header (base64 per RFC 1864) computed over the exact served bytes; when the two disagree, the header is authoritative.

• message_ids: array of string

  Chat message IDs this file is attached to. A file can be referenced by multiple messages.

• mime_type: string or null

  MIME type of the file's preferred downloadable variant (e.g. 'application/pdf'). May be null for files with no downloadable content (e.g. code-interpreter outputs).

• size_bytes: number or null

  Size in bytes of the file's preferred downloadable variant, if known
