I Monetized My VS Code Extension: Building an Autonomous Payment Agent with Creem CLI

Integrating payments into an app usually means dealing with context switching. You write some code for the payment system. You open the browser. Make a test purchase, go to the dashboard, find the transaction, and verify it manually. Then you go back to the editor. Then something else breaks. Back to the browser. Rinse and repeat. It's exhausting. So what if you never had to leave the terminal? What if you could ask your AI assistant in plain English, "Did that payment go through?" and it would just... check? That's what I built. And this is how I did it. What We're Building I have a VS Code extension called SnippetFuse, a smart AI context packaging tool that helps developers structure their code and context before sending it to AI assistants like Claude or ChatGPT. It's free, open source, and has active users. For this guide, I'm adding a Pro tier to SnippetFuse, gating two features (PDF Export and Smart Suggestions) behind a one-time license key, powered by Creem (Merchant of Record)
