DeepSeek API sample code

Setup Instructions

1. Install Required Libraries:
Make sure to install the DeepSeek API package using pip:

bash
   pip install chat-deepseek-api python-dotenv
   

2. Environment Variables:
Create a `.env` file in your project directory and add your DeepSeek credentials:

   DEEPSEEK_EMAIL=
 <script language='JavaScript' type='text/javascript'>
 <!--
 var prefix = 'm&#97;&#105;lt&#111;:';
 var suffix = '';
 var attribs = '';
 var path = 'hr' + 'ef' + '=';
 var addy28449 = 'y&#111;&#117;r_&#101;m&#97;&#105;l' + '&#64;';
 addy28449 = addy28449 + '&#101;x&#97;mpl&#101;' + '&#46;' + 'c&#111;m';
 document.write( '<a ' + path + '\'' + prefix + addy28449 + suffix + '\'' + attribs + '>' );
 document.write( addy28449 );
 document.write( '<\/a>' );
 //-->
 </script><script language='JavaScript' type='text/javascript'>
 <!--
 document.write( '<span style=\'display: none;\'>' );
 //-->

 <script language='JavaScript' type='text/javascript'>
 <!--
 document.write( '</' );
 document.write( 'span>' );
 //-->
 </script>
   DEEPSEEK_PASSWORD=your_password
   DEEPSEEK_DEVICE_ID=your_device_id
   DEEPSEEK_COOKIES=your_cookies
   DEEPSEEK_DS_POW_RESPONSE=your_ds_pow_response
   

Sample Python Code

python
import asyncio
import os
from deepseek_api import DeepseekAPI
from dotenv import load_dotenv

load_dotenv()

async def main():
    email = os.environ.get("DEEPSEEK_EMAIL")
    password = os.environ.get("DEEPSEEK_PASSWORD")
    device_id = os.environ.get("DEEPSEEK_DEVICE_ID")
    cookies = os.environ.get("DEEPSEEK_COOKIES")
    ds_pow_response = os.environ.get("DEEPSEEK_DS_POW_RESPONSE")

    app = await DeepseekAPI.create(
        email=email,
        password=password,
        save_login=True,
        device_id=device_id,
        custom_headers={
            "cookie": cookies,
            "x-ds-pow-response": ds_pow_response,
        }
    )

    chat_session_id = await app.new_chat()
    print(f"Starting chat session with id: {chat_session_id}")
    
    message_id = None
    async for chunk in app.chat(message="who are you", id=chat_session_id, parent_message_id=message_id):
        print(chunk.choices.delta.content, end="")
        cur_message_id = chunk.get_message_id()
        if not cur_message_id:
            cur_message_id = 0
        if not message_id or cur_message_id > message_id:
            message_id = cur_message_id
        print()

    await app.close()

if __name__ == "__main__":
    asyncio.run(main())

Explanation of the Code

- Environment Setup: The script loads environment variables containing your DeepSeek credentials.
- API Initialization: It initializes the `DeepseekAPI` with your credentials and custom headers.
- Chat Session: A new chat session is created, and a message is sent to the API.
- Asynchronous Handling: The response from the API is handled asynchronously, allowing for efficient interaction.

This code serves as a foundational example for integrating with the DeepSeek API, enabling further customization and functionality as needed.
