Universal AI Gateway Integration Guide

1. Gateway Base URL & Authentication

Configure your client to point to the Lemas.AI gateway endpoint. Set your bearer token to your generated Lemas.AI API key.

import OpenAI from "openai";

const lemas = new OpenAI({
  baseURL: "https://api.lemas.io.vn/v1",
  apiKey: process.env.LEMAS_API_KEY,
});

const response = await lemas.chat.completions.create({
  model: "deepseek/deepseek-r1", // or "anthropic/claude-3-7-sonnet", "openai/gpt-4o"
  messages: [
    { role: "system", content: "You are an autonomous coding agent." },
    { role: "user", content: "Implement a low-latency cache in Go." },
  ],
});

console.log(response.choices[0].message.content);

import Anthropic from "@anthropic-ai/sdk";

const lemas = new Anthropic({
  baseURL: "https://api.lemas.io.vn/v1",
  apiKey: process.env.LEMAS_API_KEY,
});

const message = await lemas.messages.create({
  model: "claude-3-7-sonnet",
  max_tokens: 1024,
  messages: [{ role: "user", content: "Design agent multi-step workflow." }],
});

console.log(message.content[0].text);
