For Veeam Backup and Replication REST APIs, x-api-version header (for example 1.3-rev1) can be obtained from a REST API?

I noticed that every REST API request, including the access token request (POST /api/oauth2/token), requires the x-api-version header (for example 1.3-rev1).

So I wanted to check if is there any REST API endpoint that returns the supported x-api-version (or REST API revision) without requiring the x-api-version header?

    If you go to the rest API URL you can see the versions.

      You may find this helpful. It’s the collector script. It discovers the latest version by probing known swagger paths. I don’t think there is a dedicated endpoint that enums them, or at least I haven’t seen it yet if there is.
