REST API: information about configuration and state of the node, stopping the node

There are two groups of methods to get information about the node configuration:

  • node - obtaining basic configuration parameters of a node, information about node state, stopping a node, changing a logging level;

  • anchoring - the GET /anchoring/config query, which returns the anchoring section of the node configuration file.

To get the basic configuration parameters of a node, there are both methods that require authorization and open methods.

node group:
