This lightweight HTTP library will efficiently handle your API communications.

Making API Requests with Python

Crafting Your First DeepSeek API Request

Open your code editor (such as Visual Studio Code) and create a new Python file. Let’s name it deepseek.py. In this file, you’ll write the code to send a request to the DeepSeek API.

Now for the exciting part: writing code to interact with DeepSeek! Here's a simple Python implementation:

import requests

# Replace with your OpenRouter API key
API_KEY = 'your_openrouter_api_key'
API_URL = 'https://openrouter.ai/api/v1/chat/completions'

# Define the headers for the API request
headers = {
    'Authorization': f'Bearer {API_KEY}',
    'Content-Type': 'application/json'
}

# Define the request payload (data)
data = {
    "model": "deepseek/deepseek-chat:free",
    "messages": [{"role": "user", "content": "What is the meaning of life?"}]
}

# Send the POST request to the DeepSeek API
response = requests.post(API_URL, json=data, headers=headers)

# Check if the request was successful
if response.status_code == 200:
    print("API Response:", response.json())
else:
    print("Failed to fetch data from API. Status Code:", response.status_code)

Save this script as deepseek.py and run it using:

python deepseek.py

If everything is configured correctly, you should see a response from DeepSeek in your terminal.
