The official link to download macOS Ventura installer app:

macappstores://apps.apple.com/app/macos-ventura/id1638787999?mt=12

However, this only works on a compatible mac with createinstallmedia command.

The createinstallmedia command is a built-in macOS tool that allows you to create a bootable USB installer from a macOS installer app . This is incredibly useful for performing a clean installation of macOS, troubleshooting your system, or installing the OS on multiple Macs without having to download the large installer each time

sudo /Applications/Install\ macOS\ Ventura.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume

sudo: Runs the command with administrator privileges.

/Applications/Install\ macOS\ Ventura.app/...: This is the full path to the createinstallmedia tool inside the Ventura installer you downloaded. The backslashes tell the Terminal to treat the spaces in the folder name as part of the path .

--volume /Volumes/MyVolume: This part tells the tool which drive to turn into the installer
