Node API

General Information

Each API call will return the result in JSON format. There are 3 objects with every response:

• status This is the status of the request. It will either be ok or error.
• data This is the contents of the request. It can be a string, array, object or numeric value.
• coin This is the current coin. It is used to determine forks or testnets.

The parameters must be sent either as POST['data'], a json encoded array or independently as GET parameters.
