How do I call the Model API from an Express server?

import express from "express";
import OpenAI from "openai";

const app = express();
app.use(express.json());
const client = new OpenAI({
  baseURL: "https://api.gateway.clatterlabs.xyz/v1",
  apiKey: process.env.CLATTER_API_KEY,
  defaultHeaders: { "X-Clatter-Account": process.env.CLATTER_ACCOUNT_ID },
});

app.post("/ask", async (req, res) => {
  try {
    const r = await client.chat.completions.create({
      model: "supercosmos-flash",
      messages: [{ role: "user", content: req.body.question }],
    });
    res.json({ answer: r.choices[0].message.content, usage: r.usage });
  } catch (e) {
    res.status(e.status ?? 500).json({ error: e.code ?? "error" });
  }
});
app.listen(3000);

Good to know#

• Keep keys on your server, never in a browser or mobile app. Why
• If calls fail unexpectedly, check status.clatterlabs.com before debugging further.
• Retry only 429 and 5xx errors, with backoff; honour Retry-After when it's sent. Which errors to retry
