How I can use the API on version 1.12.3 ?
Can you elaborate on what you are trying to do or what issue you faced ?
Yes, sorry ;
On old version I have use telegraf configured using “curl 'https://api.storj.io/contacts/Node ID” to get infos about node but doesn’t work anymore, I would like to know how I can get this info, if is still possible.
That was from the old v2 network. You can make api calls on the nodes themselves now. Try
(if looking from the same machine as the node).
