/fine-tunes	Manage fine-tuned models	POST

To authenticate, include your API key in the request header like this:

Authorization: Bearer YOUR_API_KEY

First API Test

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:

• 200 status code
• A JSON payload containing generated text
• A unique request ID

You can track your API usage - such as request counts, token usage, response times, and errors - via the dashboard.

API Features

Let's dive into the standout features of Grok's API and how you can make the most of them.

Model Types and Uses

Grok offers specialized models tailored for various applications. Its primary model, grok-beta, enables real-time integration with current X platform data .

Here’s what the platform can do:

• Text completion and generation: Perfect for crafting responses or generating content.
• Real-time information processing: Quickly processes and integrates up-to-date data.
• Vision capabilities: Available through Grok Vision Beta for image-based tasks.
• Streaming responses: Get outputs in real-time as the model processes your request.

API Settings

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.

Error Management

After setting up your parameters, managing errors effectively is key to smooth integration. Below are common error scenarios and how to handle them:

1. Authentication Errors (401)
   Ensure your API key is valid and correctly configured in XAI_API_KEY.
2. Rate Limiting (429)
   Use exponential backoff to handle rate limits:

   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)
   

3. Custom Error Codes
   Some unique error codes and their fixes:

   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 logging and monitoring for your API responses. This helps you spot recurring issues and address them before they impact your application.

Implementation Guide

Learn how to integrate Grok's API with clear, practical examples.

Code 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

For n8n workflow automation, use the following configuration:

{
    "node": "Grok",
    "credentials": {
        "grokApi": {
            "apiKey": "YOUR_API_KEY"
        }
    },
    "parameters": {
        "model": "grok-beta",
        "message": "Analyze this data",
        "temperature": 0.4,
        "maxTokens": 500
    }
}

Once the code is in place, focus on refining your prompts for better results.

Prompt Writing Tips

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:

• Be clear about what you want to achieve.
• Add relevant context to guide the response.
• Specify the desired output format.
• Highlight any constraints or special considerations.

Output Adjustment

Here are some ways to fine-tune your API responses:

1. Control the Response Format
   Use precise parameters in your API calls. Since the Grok 2 API costs $2 per million input tokens and $10 per million output tokens , optimizing your requests can save money.
2. Improve Quality
   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
   

3. Boost Performance
   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 .

Advanced Usage

Building on Grok's basic API features, advanced integrations can improve both system responsiveness and overall functionality.

Real-Time Response Setup

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)}")

Function Calls and Tools

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 .

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 .

Performance Optimization

Grok exclusively uses gRPC instead of REST API . For better performance, keep the following in mind:

1. Request Management

Implement robust error handling to manage rate limits effectively .

2. Data Processing

• Sanitize all input to guard against injection attacks.
• Batch process multiple requests to improve efficiency.
• Monitor token usage and adjust for optimal performance.

3. Security Considerations

Ensure compliance with privacy laws and Grok 3's data policies . 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
