 ### Internal endpoints

+Swagger docs for internal endpoints are served per service. I.e. there's one for
+`brig`, one for `cannon`, etc.. This is because Swagger doesn't play well with
+multiple actions having the same combination of HTTP method and URL path.

-
-Request execution does not work as Swagger expects a single target host whereas

-
-Displayed paths are prefixed by the service name (e.g. `/<brig>`). This is

-path and method. Though, some paths (e.g. `/i/status`) exist on more than one
-service. To use the a path, remove the prefix.
