Hello,
thank you for your post. At the moment it is only possible to GET data from the api. But I am working very hard to implement other methods like POST, PUT and DELETE. It costs a lot of time to test everything and implement the different validators for the different Nodes and its fields.
The API was introduced to myself for one of my projects. So the returned data is different from the official API. If you need more output I can implement it in a few hours.
