That OpenAI Call From Your Browser Is Failing. Here's Why. You're fetching from directly in the browser. It works in de. Then production hits you with a CORS error. Or a 401. Or worse - a silent failure where the request goes out but never comes back. Sound familiar? Let's cut through the noise. Here's what's actually breaking. The Problem Browser JavaScript can't call OpenAI directly. OpenAI's API doesn't set Access-Control-Allow-Origin headers for browser origins. That's by design - they don't want API keys sitting in client-side code. But you already know that. The issue is deeper.
