Can I use FastAPI and SQLite for user account management in a userscript?▼

Yes, you can use FastAPI and SQLite for user account management in a userscript. This skill integrates FastAPI to create API endpoints for authentication and SQLite to store user data, enabling secure account management and usage tracking for Tampermonkey scripts.

What is the best way to monetize a Tampermonkey userscript?▼

The best way to monetize a Tampermonkey userscript is integrating a backend API for user authentication and recharge codes. This approach secures script features behind a paid wall, managing accounts and tracking usage through API endpoints.

How do I add recharge codes to my userscript backend?▼

To add recharge codes to your userscript backend, you implement API endpoints that generate and validate codes for user balance top-ups. This skill handles recharge code logic, connecting the FastAPI backend with the SQLite database to track user credits.

Do I need a FastAPI backend to deploy a paid userscript?▼

You need a backend framework like FastAPI to deploy a paid userscript because it handles user authentication, API access, and recharge code management. Without a backend, your Tampermonkey script cannot securely verify payments or track usage.

How does API usage tracking work for a Tampermonkey userscript?▼

API usage tracking for a Tampermonkey userscript works by sending requests from the frontend script to FastAPI backend endpoints, which log activity in an SQLite database. This setup ensures only authenticated users access paid features.
