Retrieves API help for paths. All endpoints in Vault provide built-in help

in markdown format. This includes system paths, secret engines, and auth

methods.

Get help for the thing mounted at database/:
|

|
$ vault path-help database/
|
|
|

The response object will return additional paths to retrieve help:

|

$ vault path-help database/roles/
|

Each secret engine produces different help output.

If -format is specified as JSON, the output will be in OpenAPI format.
