## 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)

### Header Parameters

- `"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

- `filename: string`

  Display name of the file, if set

- `md5: string`

  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`

  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`

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

curl https://api.anthropic.com/v1/compliance/apps/chats/files/$CLAUDE_FILE_ID \
    -H "Authorization: Bearer $ANTHROPIC_COMPLIANCE_API_KEY"
