# Get a media preview

> Get a short-lived private URL to view approved media.

Read access: a read-enabled personal or team REST API key, or a signed-in user. OAuth clients use the corresponding MCP tool through /mcp.

Get a short-lived private URL to view approved media.

Only approved, ready media from this team can be previewed. The URL is temporary and is not a permanent public attachment URL.

MCP clients can use [`get_media_preview`](/mcp-reference/get_media_preview) for this operation.
