Add a test for this endpoint

[atolopko-czi]

LGTM but let's also add a simple test to test_api_v3.py, to keep code coverage from falling.

Also note that I added a follow-up task to the issue to update the deployment checklist.

[ebezzi]

I will add a test, but note that it won't guarantee the endpoint to work since it's environment/infra dependent.
