I need to secure an API with API Keys. I’m looking for a finished solution that does the following: 1. Can automatically create an API key when a user creates a paid subscription in Stripe 2. Tracks usage of this API key so the user doesn’t go above quota 3. Implements global rate-limits per api key I have found moesif.com but its a bit pricy, I can run some own infrastructure if it means lower cost. Does anyone know of a tool like this?
