You
I need an API route in my Expo app that securely calls OpenAI and doesn't expose my API key.
Agent
I'll create an 'app/api/ai+api.ts' route for you. I'll implement a POST handler that retrieves your OpenAI key from 'process.env' on the server, proxies the request to the OpenAI API, and returns the response to your client. This ensures your key stays secure on EAS Hosting and never reaches the user's device.
