Node Status​

Provides the status of the specified sentnode address.

Node Status

/home/${USER}/sentnode-status.sh
#!/bin/bash

# Fetching the JSON data from the API
api_response=$(curl -s https://api.sentinelgrowthdao.com/sentinel/nodes/sentnode1rx7kjsvhvklcluhu9zl6hswrau06vh3ll7gthr)

# Extracting the remote URL from the JSON response
remote_url=$(echo "$api_response" | jq -r '.node.remote_url')

# Fetching the status from the remote URL
status_response=$(curl -k "$remote_url/status" | jq '.')

echo "Status from $remote_url:"
echo "$status_response" | jq '.'

RPC Countries​

Lists the countries of the RPC Nodes.
