Setup Guide
This guide walks you through setting up and testing API access for Grok. Follow these steps to create your account, authenticate, and start using Grok's API.
Keep in mind that as of April 2025, the Grok 3 API is yet to come out. When it’s out, we’ll integrate it as a direct, plug-and-play integration without the need for API tokens, account credentials, or complex code setup.
Right now, you can only connect Grok 2 to your tools via the API. For example, you can send a request to Grok 2 via the HTTP request node or Javascript code to interact with and automate communication with this model in your automation scenarios. Check out our API integration guide!
Start by registering on the xAI Developer Portal. Choose your preferred access tier:
Once registered, generate your API keys: a public Access Key and a private Secret Key. These keys are essential for authenticating your API requests.
With your keys ready, you're set to proceed to API configuration.
Grok's REST API uses JSON for communication. The base URL for all requests is:
https://api.grok.xai.com/v1
Here are the main endpoints:
| Endpoint | Description | Request Method |
|---|---|---|
/models |
List available models | GET |
/completions |
Generate text completions | POST |
/embeddings |
Create text embeddings | POST |
/fine-tunes |
Manage fine-tuned models | POST |
To authenticate, include your API key in the request header like this:
Authorization: Bearer YOUR_API_KEY
Once your setup is complete, test it with a simple API call. Use the following cURL command to verify everything is working:
curl https://api.grok.xai.com/v1/completions \
-H "Authorization: Bearer YOUR_API_KEY" \
-H "Content-Type: application/json" \
-d '{
"model": "grok-1",
"prompt": "Hello, Grok!",
"max_tokens": 50
}'
A successful response will include:
You can track your API usage - such as request counts, token usage, response times, and errors - via the dashboard.
Let's dive into the standout features of Grok's API and how you can make the most of them.
Grok offers specialized models tailored for various applications. Its primary model, grok-beta, enables real-time integration with current X platform data [1].
Here’s what the platform can do:
By the way, we have a series of templates that can solve all of these tasks. No more need for endless scrolling the news websites or analyzing tons of data, or even writing any content — AI automation can now do it for you. For inspiration, check out our collection of AI templates for scenarios!
You can fine-tune responses by adjusting key parameters. Here’s a quick guide:
| Parameter | Description | Suggested Value |
|---|---|---|
| temperature | Adjusts randomness of the output | Lower (0.2–0.4) for factual responses |
| max_tokens | Limits the output length | Set based on your needs |
| top_p | Controls diversity in responses | 0.1–0.9, depending on your creativity needs |
| frequency_penalty | Reduces repetitive words | 0.1–0.8 for varied vocabulary |
| presence_penalty | Avoids repeating topics | 0.1–0.8 for topic diversity |
You can apply these settings directly using the Grok Python SDK:
import xai_sdk
client = xai_sdk.Client()
response = client.sampler.sample(
prompt="Your prompt",
temperature=0.4,
max_tokens=100
)
This setup gives you control over how the API responds, whether you're aiming for creative or factual outputs.
After setting up your parameters, managing errors effectively is key to smooth integration. Below are common error scenarios and how to handle them:
XAI_API_KEY.
import time
import random
def handle_rate_limit():
base_delay = 1
max_retries = 3
for attempt in range(max_retries):
try:
# Your API call here
return response
except RateLimitError:
delay = (base_delay * 2 ** attempt) + random.uniform(0, 0.1)
time.sleep(delay)
| Code | Meaning | Resolution |
|---|---|---|
| 498 | Flex Tier Capacity Exceeded | Wait and retry later |
| 499 | Request Cancelled | Check logs for the issue |
| 502 | Bad Gateway | Retry using exponential backoff |
| 503 | Service Unavailable | Wait for the service to recover |
Set up detailed monitoring for your API responses. This will help you identify recurring issues and resolve them before they impact your application. This is especially important if you are building complex automation on Latenode, consisting of multiple requests to the Grok API, as well as numerous execution branches, triggers, and so on.
Learn how to integrate Grok's API with clear, practical examples.
Here's a Python example of a web crawler built with Grok-2 and Firecrawl:
import os
from dotenv import load_dotenv
from firecrawl import Crawler
from xai_sdk import Client
load_dotenv()
grok_api_key = os.getenv('GROK_API_KEY')
client = Client(api_key=grok_api_key)
crawler = Crawler(
objective="Extract product information",
max_pages=100,
output_format="json"
)
def analyze_content(content):
response = client.chat.completions.create(
model="grok-beta",
messages=[
{"role": "system", "content": "Extract key product details"},
{"role": "user", "content": content}
],
temperature=0.2
)
return response.choices[0].message.content
Writing effective prompts requires clarity and structure. Use the table below for guidance:
| Prompt Type | Structure Pattern | Application |
|---|---|---|
| Contextual | "Given [context], analyze [specific aspect]" | For targeted analysis |
| Chain-of-thought | "Think step-by-step about [problem]" | For complex reasoning |
| Role-based | "As a [role], provide [specific output]" | For specialized responses |
To create strong prompts:
Why bother with manual prompt engineering if you can automate it? Check out our AI automation template to enhance your prompts based on your guidelines. No more hassle with prompt formatting — let AI handle it for you.
Here are some ways to fine-tune your API responses:
Use precise parameters in your API calls. Since the Grok 2 API costs $2 per million input tokens and $10 per million output tokens [2], optimizing your requests can save money.
Validate responses with a custom function. For instance:
def validate_response(response, criteria):
if not meets_criteria(response):
# Retry with adjusted parameters
return retry_request(
temperature=temperature - 0.1,
max_tokens=max_tokens + 100
)
return response
When handling large tasks, batch processing can save time. For example, Grok 3 processed a 38-page document in seconds, compared to the two days it would take manually [3].
Building on Grok's basic API features, advanced integrations can improve both system responsiveness and overall functionality.
Grok's API supports real-time responses, making it ideal for interactive applications. Its streaming feature sends output token by token, ensuring a more dynamic user experience.
Here's an example of how to set up streaming responses with ChainLit and the Grok 2 API:
import chainlit as cl
from openai import AsyncOpenAI
import os
client = AsyncOpenAI(
api_key=os.getenv("XAI_API_KEY"),
base_url="https://api.x.ai/v1",
)
@cl.on_message
async def main(message: cl.Message):
msg = cl.Message(content="")
try:
stream = await client.chat.completions.create(
messages=[{"role": "user", "content": message.content}],
model="grok-beta",
stream=True,
temperature=0.7
)
async for part in stream:
if token := part.choices[8].delta.content:
await msg.stream_token(token)
await msg.update()
except Exception as e:
await msg.update(content=f"Error: {str(e)}")
Grok's tool-use feature allows you to execute functions programmatically using structured JSON outputs. This is especially useful for tasks like data fetching, function execution, and parameter parsing [5].
| Tool Type | Purpose | Implementation |
|---|---|---|
| Data Fetching | Access external data in real-time | Custom API integrations |
| Function Execution | Perform operations programmatically | JSON-structured calls |
| Parameter Parsing | Convert natural language to structured data | Automated parameter extraction |
To ensure accuracy, define clear function descriptions and parameters. Incorporate error-handling mechanisms for scenarios where tools fail, and include fallback options to standard chat completions [5].
Grok exclusively uses gRPC instead of REST API [1]. For better performance, keep the following in mind:
1. Request Management
Implement robust error handling to manage rate limits effectively [4].
2. Data Processing
3. Security Considerations
Ensure compliance with privacy laws and Grok 3's data policies [4]. Use key management services to securely store API keys.
"Groq API endpoints support tool use for programmatic execution of specified operations through requests with explicitly defined operations. With tool use, Grok API model endpoints deliver structured JSON output that can be used to directly invoke functions from desired codebases." - Groq documentation [5]
Grok's API is designed to enhance AI model performance and ease of integration. With its high-speed gRPC framework and official Python SDK, it offers a strong foundation for developers looking to incorporate AI into their workflows.
| Feature | Capability | Implementation Note |
|---|---|---|
| Context Length | 128,000 tokens | Ideal for processing large documents |
| Real-time Data | X platform integration | Enables access to up-to-date information |
| API Compatibility | OpenAI/Anthropic compatible | Simplifies migration processes |
| Performance | ELO score above 1400 | Achieves top-tier benchmark results |
In testing, Grok excelled in specialized fields, proving its reliability and seamless integration potential. Notably, the model scored 59% on Hungarian high school mathematics entrance exams [1], while outperforming competitors like Gemini-2 Pro and Claude 3.5 Sonnet in mathematics, science, and coding challenges within the LMSYS Arena [7].
"to understand the universe. We want to answer the biggest questions: Where are the aliens? What's the meaning of life? How does the universe end? To do that, we must rigorously pursue truth." – Elon Musk [7]
These results make Grok a strong candidate for integrating advanced AI capabilities into existing systems.
The performance benchmarks above set the stage for an efficient onboarding experience. During the public beta, users are provided with $25 in monthly API credits [6]. Access requires an X Premium+ subscription ($40/month), while the SuperGrok tier is available for $50/month [7].
To get started, you'll need the following resources:
pip install xai-sdk
XAI_API_KEY
Migrating to Grok is straightforward. Simply update the base URL to https://api.x.ai/v1 and install the SDK [6]. For the best results, take advantage of advanced features like function calling and system prompts, and always prioritize secure API key management [8].
