LLM API Quick Start

Send your first API request in 5 minutes. ViLao API is OpenAI-compatible — drop-in replacement for openai.com endpoints.

Get your Consumer Key

Go to Dashboard > API Keys, click Create new key, and copy the sk-xxx token.

Treat the key like a password. The platform is not responsible if it leaks.

First curl request

curl

curl https://api.vilao.vn/v1/chat/completions \
  -H "Authorization: Bearer $VILAO_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "claude-4.7-sonnet",
    "messages": [{"role": "user", "content": "Hello!"}]
  }'

Python (openai SDK)

from openai import OpenAI

client = OpenAI(
    api_key="sk-xxx...",
    base_url="https://api.vilao.vn/v1",
)

response = client.chat.completions.create(
    model="gpt-5.5",
    messages=[{"role": "user", "content": "Hi"}],
)
print(response.choices[0].message.content)

Node.js

import OpenAI from "openai";

const client = new OpenAI({
  apiKey: process.env.VILAO_API_KEY,
  baseURL: "https://api.vilao.vn/v1",
});

const r = await client.chat.completions.create({
  model: "gemini-3.1-pro",
  messages: [{ role: "user", content: "Hi" }],
});
console.log(r.choices[0].message.content);
