OpenAI TypeScript SDK with MagmaRouter

The Node OpenAI client takes a baseURL in its constructor. Set it to MagmaRouter and your chat.completions calls route through the gateway.

Base URL

https://api.magmarouter.com/v1

API key

Get one, starts sk-mr-

Example model

glm-5.3-xploded

baseURL and apiKey

// npm install openai
import OpenAI from "openai";

const client = new OpenAI({
  baseURL: "https://api.magmarouter.com/v1",
  apiKey: "sk-mr-...",
});

const resp = await client.chat.completions.create({
  model: "glm-5.3-xploded",
  messages: [{ role: "user", content: "Hello" }],
});
console.log(resp.choices[0].message.content);

Use baseURL: "https://api.magmarouter.com/v1" and apiKey for the key, or set OPENAI_BASE_URL and OPENAI_API_KEY in the environment. Stay on chat.completions.create; the Responses API is not served.
