Quick Start

Get up and running with the LW AI API in just a few steps.

Step 1: Get an API Key

Contact support@linkwo.com to obtain an API key. See Authentication for details.

Step 2: Make Your First Request

Using cURL

curl https://openapi.linkwo.ai/v1/chat/completions \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "deepseek/deepseek-v4-pro",
    "messages": [
      {"role": "user", "content": "Say hello in 5 languages"}
    ]
  }'

Using Python (OpenAI SDK)

pip install openai

from openai import OpenAI

client = OpenAI(
    base_url="https://openapi.linkwo.ai/v1",
    api_key="YOUR_API_KEY"
)

response = client.chat.completions.create(
    model="deepseek/deepseek-v4-pro",
    messages=[
        {"role": "user", "content": "Say hello in 5 languages"}
    ]
)

print(response.choices[0].message.content)

Using Node.js (OpenAI SDK)

npm install openai

import OpenAI from 'openai';

const client = new OpenAI({
  baseURL: 'https://openapi.linkwo.ai/v1',
  apiKey: 'YOUR_API_KEY',
});

const response = await client.chat.completions.create({
  model: 'deepseek/deepseek-v4-pro',
  messages: [{ role: 'user', content: 'Say hello in 5 languages' }],
});

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

Step 3: Try Streaming

For real-time responses, use streaming:

stream = client.chat.completions.create(
    model="deepseek/deepseek-v4-pro",
    messages=[{"role": "user", "content": "Write a poem about AI"}],
    stream=True
)

for chunk in stream:
    if chunk.choices[0].delta.content:
        print(chunk.choices[0].delta.content, end="", flush=True)
