Can orbs be aware of their version when deployed?

I have a use case whereby I would like to trigger an orb re-build on a specific tag.

That tag is re-used in other places and it would be easier if I could have a CIRCLECI_ORB_VERSION or similar value to refer to within the orb package to do operations like curl https://example.com/<tag>/file.txt as the command run.

Does such a solution exist?
