I made a simple automation that checks multiple X accounts once a day and saves the follower count in Airtable.
It also records the change from the previous day so you can see rises or dips across accounts. It uses n8n with a daily cron, calls the X API, and upserts the data to Airtable.
This automation is great for those that may run X.com agencies like for ghost writing to track performance and inform clients.
