The UCP profile on your domain

How shopping agents discover that your store supports agent checkout.

Shopping agents discover that your store supports agent checkout by requesting /.well-known/ucp on your domain. The plugin serves this file, but the content comes from Sarvex — the plugin is just the doorway.

• It’s cached for an hour, so a brief Sarvex outage doesn’t break it — your store keeps serving the last known-good version.
• It never requires authentication and never redirects; it just returns the file.
• You don’t maintain or edit this yourself.
