Getting Started: Your First “Hello World” with the DeepSeek API Platform

So you’ve heard the buzz about DeepSeek’s AI models — from intelligent chat to code generation — and you’re ready to try it out. Great news: you can integrate and run your first API call in under 5 minutes.

This guide will walk you step-by-step through your first “Hello World” project using the DeepSeek API Platform, whether you prefer Python, Node.js, or a simple HTTP request.

---

Step 1: Get Your API Key

1. Visit the DeepSeek Developer Console.
2. Create a free account or log in.
3. Go to API Keys → Generate New Key.
4. Copy your key — you’ll need it for authentication.

⚠️ Important: Keep your API key private. Never hard-code it into client-side code or share it publicly.

---

Step 2: Choose Your Language

You can access the DeepSeek API via:

• ✅ Python SDK (pip install deepseek)
• ✅ Node.js SDK (npm install deepseek-sdk)
• ✅ Or standard HTTPS requests (cURL/Postman)

Let’s look at all three examples.

---

Option 1: Python Example

from deepseek import DeepSeek

client = DeepSeek("YOUR_API_KEY")

response = client.chat.create(
    model="deepseek-chat",
    messages=[{"role": "user", "content": "Hello, DeepSeek!"}]
)

print(response.output)

Output:

Hello! How can I assist you today?

---

Option 2: Node.js Example

import DeepSeek from "deepseek-sdk";

const client = new DeepSeek("YOUR_API_KEY");

const response = await client.chat.create({
  model: "deepseek-chat",
  messages: [{ role: "user", content: "Hello, DeepSeek!" }]
});

console.log(response.data.output);

Output:

Hello! How can I assist you today?

---

Option 3: Direct API Call (cURL)

curl https://api.deepseek.international/v1/chat \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "deepseek-chat",
    "messages": [{"role": "user", "content": "Hello, DeepSeek!"}]
  }'

---

Step 3: Test in the Playground

Before integrating into your app, try the DeepSeek Playground.
Here you can:

• Experiment with model parameters like temperature and max tokens
• View request and response JSON
• Export working code snippets directly into your project

---

Step 4: Integrate with Your App

Once your API call works, you can easily connect it to:

• Your web backend for chat or automation
• A Slack bot or Discord bot
• A CRM system for intelligent replies
• A frontend widget powered by DeepSeek responses

If you’re building something interactive, remember to handle rate limits and response streaming for optimal performance.

---

Step 5: Monitor and Optimize

Check the DeepSeek Dashboard to:

• Monitor token usage
• Analyze response times
• View error logs
• Upgrade to higher throughput tiers as you scale

---

Common Setup Issues

Issue	Cause	Solution
401 Unauthorized	Invalid API Key	Double-check your credentials
429 Too Many Requests	Rate limit exceeded	Implement queuing or upgrade plan
Invalid JSON	Formatting error	Validate payload structure
