Is the Migrator API demo server still in use?

I'm trying to get data for a test environment by following this guide: Currently I don't have an actual prod environment to copy data from.

I'm getting a 404 error from when I attempt to import from the demo server.

I also saw in the project's github page that the latest version added bearer token support, but it looks like the tool still only has fields for username/password.
