How to Run an Autonomous AI Newsletter with $0/month Infrastructure

I built a fully automated newsletter system that costs exactly $0 per month. It publishes to a website, sends emails, and handles paid subscriptions — all through APIs that Claude Code can call autonomously. Here's the architecture and the code. The Stack Component Service Cost Website GitHub Pages $0 Email delivery Resend API $0 (3,000/mo free) Payments Stripe $0 (3.6% per transaction) Content Markdown files $0 Build tool Node.js scripts $0 Total: $0/month. You only pay when someone pays you. Why Not Ghost/Substack/Beehiiv? I evaluated all of them: Substack : No API for posting. Can't automate. Beehiiv : Post creation API is Enterprise-only (price undisclosed). Ghost Pro : $15/month before you have any readers. Ghost self-hosted : Full API, but $6-12/month for a VPS. For a pre-revenue newsletter, paying before earning doesn't make sense.
