Method 2. Check Your API Key or Token

If your API key or token is invalid, you may encounter a 401 error from DeepSeek. In this case, you can verify your API key or token by following these steps:

• Confirm that the API key or token is accurate, formatted correctly, and free of errors.
• Check the token’s validity period to see if it has expired.
• Test the API connectivity using Postman

Also, you can choose to create a new API key to fix Error: Authentication Failed (Status 401). To do that, you can do as follows:

1. Open your browser, navigate to platform.deepseek.com, and log into your account.
2. Navigate to the API keys section.
3. Click Create new API key.
4. Name your API key and copy it immediately.
5. Next, integrate this new API key into your project.

If you still see the same error, you can try creating an environmental variable to fix the error, like:

import os

api = deepseek.connect(api_key=os.getenv(“DEEPSEEK_API_KEY”))

Method 3. Include the Required Parameters and Authentication Headers

If an API request misses or corrects required parameters or authentication headers, you can run into the DeepSeek 401 error easily. So, you need to ensure all the required parameters and the Authorization: Bearer <your_token> header are included in your API request.

Method 4. Check IP Restriction

Some APIs impose IP restrictions that restrict access to specific IP addresses or ranges. If your IP is restricted, you can receive the DeepSeek API error 401 “Authentication Fails” easily.

Therefore, you should check if the DeepSeek API has any restrictions and confirm that your IP address is permitted. You can typically find this information in the DeepSeek API Docs or in the security settings of your DeepSeek account.

Method 5. Contact DeepSeek Support

If none of the above methods can help you fix the DeepSeek error 401, the only way you can do is contact DeepSeek support and ask them to help you solve the error. To do that, you just need to do as follows:
