Get orb version as environment variable while running job

Hello!

We have authored a CircleCI orb. It’s relatively simple, this is what it does:

  • record the current CIRCLE_BRANCH, CIRCLE_PROJECT_REPONAME, CIRCLE_PROJECT_USERNAME
  • make a call to our API with the above information
  • return some value to the user to be used for other jobs

A user can use any version of the orb. We would like to identify the version of the orb that the job is using, and pass that to the API. I do not see a corresponding env var in the current list. Is there an environment variable (or could we request one) to get the version of the orb currently used?
