2. API Proxy Gateway Configuration

If you face connection timeouts or reside in regions with restricted access, route requests through a custom gateway proxy. Configure the baseURL property inside the OpenAI client instance:

import OpenAI from "openai";

const openai = new OpenAI({
  apiKey: process.env.OPENAI_API_KEY,
  // Reroutes traffic to an authorized gateway proxy
  baseURL: "https://your-custom-authorized-proxy.com/v1", 
});
