Grok3 is cool, smart, and useful, but there is no official API available. This is an unofficial Python client for interacting with the Grok 3 API. It leverages cookies from browser requests to authenticate and access the API endpoints.
Follow these steps to get started with the Grok3 API client.
Clone this repository to your local machine:
git clone https://github.com/mem0ai/grok3-api.git
Navigate to the project directory, create a virtual environment, and install the package:
cd grok3-api
virtualenv pyenv
source pyenv/bin/activate
pip install .
To use this client, you need to extract authentication cookies from a browser session:
- Open grok.com in your browser.
- Log in if you aren't already logged in.
- Open the browser's developer tools (e.g., F12 or right-click > Inspect).
- Go to the "Network" tab and filter for requests containing the new-chat endpoint (e.g., https://grok.com/rest/app-chat/conversations/new).
- Right-click the request, select "Copy as cURL," and paste it somewhere.
From the curl command, extract the following cookie values from the -H 'cookie: ...' header:
- x-anonuserid
- x-challenge
- x-signature
- sso
- sso-rw
Example cookie string from a curl command:
-H 'cookie: x-anonuserid=ffdd32e1; x-challenge=TkC4D...; x-signature=fJ0U00...; sso=eyJhbGci...; sso-rw=eyJhbGci...'
Pass the extracted cookie values to the GrokClient and send a message:
from grok_client import GrokClient
# Your cookie values
cookies = {
"x-anonuserid": "ffdd32e1",
"x-challenge": "TkC4D..",
"x-signature": "fJ0...",
"sso": "ey...",
"sso-rw": "ey..."
}
# Initialize the client
client = GrokClient(cookies)
# Send a message and get response
response = client.send_message("write a poem")
print(response)
If you want Grok to remember conversations, you can integrate it with Mem0. Mem0 provides a memory layer for AI applications.
pip install mem0ai
from mem0 import Memory
memory = Memory()
# for user alice
result = memory.add("I like to take long walks on weekends.", user_id="alice")
# Retrieve memories
related_memories = memory.search(, user_id="alice")
print(related_memories)
