ファイルメタデータの取得

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

チャットメッセージで参照されているファイルのメタデータを、ファイルコンテンツをダウンロードせずに取得します。バイトデータをダウンロードするには、兄弟エンドポイントである /content を使用してください。

Path parameters
claude_file_id: string

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

Headers
"x-api-key": optional string
Returns
id: string

File ID

filename: string or null

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.

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).
