How to Get Qwen API Key? (Step-by-Step Guide)

If you want to access Alibaba Cloud’s Qwen API, you’re in the right place.

This guide will take you through each step in a clear and easy-to-understand way so you can get your API key and start using Qwen quickly.

Whether you’re a beginner or an experienced developer, you’ll find this guide helpful.

What is the Qwen API?

Qwen is an advanced AI-powered language model developed by Alibaba Cloud.

It can be used for various applications like chatbots, content generation, language translation, and much more.

To use Qwen’s features, you need an API key, which acts as a unique identifier for accessing the service securely.

Ready? Let’s go!

Step 1: Set Up Your Alibaba Cloud Environment

The first step is to ensure your Alibaba Cloud account is ready to use the Qwen2.5-Max API. Here’s how:

Register and Activate Model Studio:

Head over to the Alibaba Cloud website and sign up for an account if you haven’t already.
Once registered, navigate to the Model Studio service and activate it. This will give you access to the Qwen2.5-Max API.

Generate an API Key: After activating the service, create an API key. This key will authenticate your requests when interacting with the Qwen2.5-Max API.

Keep this key secure: it’s essential for accessing the API.

Since the APIs of Qwen are OpenAI-API compatible, we can directly follow the common practice of using OpenAI.

Below is an example of using Qwen2.5-Max in Python:

from openai import OpenAI
import os

client = OpenAI(
    api_key=os.getenv("API_KEY"),
    base_url="https://dashscope-intl.aliyuncs.com/compatible-mode/v1",
)

completion = client.chat.completions.create(
    model="qwen-max-2025-01-25",
    messages=[
      {'role': 'system', 'content': 'You are a helpful assistant.'},
      {'role': 'user', 'content': 'Which number is larger, 9.11 or 9.8?'}
    ]
)

print(completion.choices[0].message)

Step 2: Install and Configure Apidog

Now that your environment is set up, let’s move on to configuring Apidog for API testing.

Download and Install Apidog: Visit the Apidog website and download the tool for free. It’s available for Windows, macOS, and Linux.
Create a New Project: Open Apidog and create a new project. Name it something descriptive, like “Qwen2.5-Max API Testing.”

Import or Create API Documentation: If you already have API documentation for Qwen2.5-Max, import it directly into Apidog. Otherwise, manually create the endpoints and parameters based on the API specifications provided by Alibaba Cloud.

Step 3: Make Your First POST Request to Qwen2.5-Max

With everything configured, it’s time to send your first request to the Qwen2.5-Max API. Here’s how to do it using Apidog:

Set Up the Request:

In Apidog, click on “New Request” and select the POST method.

Enter the API endpoint URL provided by Alibaba Cloud. For example:

https://api.alibabacloud.com/v1/qwen2.5-max

Add Headers:

Include the necessary headers in your request. At a minimum, you’ll need:
Authorization: Use your API key here (e.g., Bearer YOUR_API_KEY).

Content-Type: Set this to application/json.

Define the Request Body: In the body section, specify the input data in JSON format. For example:

{
  "prompt": "Explain the concept of quantum computing.",
  "max_tokens": 200
}

This tells Qwen2.5-Max what task to perform and how many tokens to generate in response.

Send the Request: Click the “Send” button in Apidog. If everything is set up correctly, you should receive a response from the API containing the generated text.
