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

"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

formatdate-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
