Make starting point of API more handsome

[KlausIllmayer]

When opening the main entry point of the API https://marketplace-api.sshopencloud.eu/api/ there is currently a not very helpful information: sending status 500 with the error message "No static resource api."

Is there a way to have here a more handsome information, like a reference to the API description: https://marketplace.sshopencloud.eu/about/api-documentation or anything else?

as part of the new API version

handsome would be nice, but we would already be happy if it is more useful. ;)
