Does the "verify" API endpoint work?

AFAICT, from the Go client source code, the Drone API should have a POST endpoint at api/repos/<owner>/<name>/verify, for verifying config signatures. However, when I try this endpoint I get a 404 back (directly or via the Go client). Is it unsupported?

I try for example the following on the command line:

$ curl -XPOST -d'{data: ""}' https://<server>/api/repos/<owner>/<name>/verify
404 page not found
