How to Get DeepSeek Free API and Supercharge Your API Development

In this article, we’ll cover everything you need to know about setting up DeepSeek Free API and integrating it with Apidog. Each step will be explained in a conversational yet technical tone, ensuring that regardless of your experience with AI or API development, you can still follow along and get your projects up and running in no time.

What is DeepSeek Free API?

DeepSeek Free API is an advanced interface that lets you tap into the capabilities of the DeepSeek language models. These models are designed to handle complex NLP tasks such as text generation, summarization, translation, and even code completion. The API is available for free (with usage limits) so that developers, startups, and AI hobbyists can experiment and build innovative applications without significant financial investment.

Key Features of DeepSeek Free API

• OpenAI Compatibility:
  DeepSeek API uses an API format that is compatible with OpenAI. This means you can use the OpenAI SDK or any software that works with the OpenAI API to access DeepSeek’s powerful language models.
• Flexible Base URL Configuration:
  You have the option to set your base URL to either https://api.deepseek.com or https://api.deepseek.com/v1. The latter is recommended for compatibility with OpenAI, although note that the “v1” here does not reflect the model’s version.
• Multiple Models in One API:
  The API supports different models for various tasks. For instance, the deepseek-chat model (upgraded to DeepSeek-V3) is used for conversational tasks, while the deepseek-reasoner model (DeepSeek-R1) is designed for advanced reasoning tasks.
• Scalability and Versatility:
  Whether you are looking to build a conversational agent or perform complex reasoning, DeepSeek’s models provide scalable performance for a wide range of applications.

How to Get Started with DeepSeek Free API

Getting started with DeepSeek Free API is simple if you follow these steps. We’ll cover the entire process from account creation to making your first API call.

Sign Up and Account Creation on the DeepSeek Platform

1. Visit the DeepSeek Website:
   Head over to DeepSeek's official website and click on the “Sign Up” button. You can register using your email or via your GitHub account for quicker access.
2. Fill Out the Registration Form:
   Provide your name, email, and create a secure password. Once you complete the registration form, you will receive a verification email.
3. Verify Your Email:
   Click on the link in the verification email to activate your account. This step is crucial as it confirms your identity and unlocks access to the developer dashboard.

Generating Your Free DeepSeek API Key

After your account is verified, the next step is to generate your unique API key:

1. Log into the API Platform:
   Navigate to the dashboard where all API-related functionalities are managed.
2. Locate the API Keys Section:
   Within the dashboard, you’ll find an “API Keys” section. Click on “Generate API Key” to create a new key.
3. Copy and Secure the API Key:
   Make sure to copy your API key and store it securely. You will need this key to authenticate your requests to the DeepSeek API.

Configuring Your API Client

One of the best aspects of DeepSeek API is its compatibility with the OpenAI API format. This means you can use the OpenAI SDK to interact with DeepSeek. Here’s how to set it up:

Install the OpenAI SDK:
If you haven’t already, install the OpenAI SDK by running:

pip3 install openai

1. Set Up Your Configuration:
   When configuring your client, specify the base URL and API key. DeepSeek recommends using https://api.deepseek.com or https://api.deepseek.com/v1 (the latter for OpenAI compatibility). Note that the “v1” does not indicate the version of the model.

Specify the Model:

• For conversational tasks, use the model parameter model="deepseek-chat". This invokes the latest version of the chat model, now known as DeepSeek-V3.
• For reasoning tasks, use model="deepseek-reasoner" to call DeepSeek-R1, the latest reasoning model.

Invoking the DeepSeek Chat API

Now, let’s see how you can make a basic API call using the OpenAI SDK to interact with DeepSeek. Below is an example Python script:

from openai import OpenAI

# Initialize the client with your DeepSeek API key and base URL
client = OpenAI(api_key="your_api_key_here", base_url="https://api.deepseek.com")

# Make a non-streaming chat completion request using the deepseek-chat model
response = client.chat.completions.create(
	model="deepseek-chat",
    messages=[
    	{"role": "system", "content": "You are a useful assistant"},
        {"role": "user", "content": "Can you explain how DeepSeek API works?"} 
	],
    stream=False  # Set to True for a streaming response
) 

# Print the response content
print(response.choices[0].message.content)

This script demonstrates how easy it is to interact with DeepSeek API. By using the OpenAI SDK, you leverage the familiar format while accessing DeepSeek’s powerful language capabilities. Adjust the prompt and parameters as needed to suit your application’s requirements.
