.I have used drahak/Restful long time ago. Last commit was 2 months ago so you should not have any problems. It provides you with more advanced router, OAuth2 and another tools to help you with building your API.
$router[] = new CrudRoute('api/v1/<presenter>/<id>/[<relation>[/<relationId>]]', 'Articles');
Also there was workshop on #posobota. Sources from API workshop can be found in fprochazka/workshop-rest-api-sandbox repository on GitHub.
Let me know if it works fine for you!
