The Pineco.de blog has a tutorial posted showing Laravel users how to append API and web routes to Eloquent models directly without the need for setting up additional route handling.

As a level zero, we can agree on using the RESTful URI scheme. That means every model has an associated route. We can perform different actions on the model, depending on the request type.

It can be a bit painful to concatenate the strings and IDs all the time, so we could append this URL as an attribute of the model. That means we could calculate the URL behind the scenes, and use it on the PHP or the JS side as well. [...] Then only difference (in this simple example) between the API and the web routes is that the API routes have a /api prefix in the URL.

The tutorial then introduces their custom Routable trait that can be included in any model to handle requests on both the API and web side (differentiated by the "api" prefix). The last step is to append the routes to the model itself using the appends Eloquent property.
