## Remarks

- Any session can call it, vault or server-level; no rights are needed. Calls without a
  session fail with `UNAUTHENTICATED`.
- In a vault session, the vault's own license is taken into account.
- Set every feature you are interested in, or `all`; the response repeats the requested features
  that are licensed.
