  }'

Method 3: Python Validation

import os
from groq import Groq

def validate_groq_key(api_key: str):
    """Validate Groq API key"""
    try:
        client = Groq(api_key=api_key)
        
        # List available models
        models = client.models.list()
        model_ids = [m.id for m in models.data]
        
        # Test with minimal completion
        completion = client.chat.completions.create(
            model="mixtral-8x7b-32768",
            messages=[
                {"role": "user", "content": "test"}
            ],
            max_tokens=5
        )
        
        return True, f"Valid - {len(model_ids)} models available"
    except Exception as e:
        error_msg = str(e)
        if "invalid" in error_msg.lower() or "401" in error_msg:
            return False, "Invalid API key"
        elif "rate" in error_msg.lower():
            return True, "Valid but rate limited"
        return False, f"Error: {error_msg}"

# Usage
is_valid, message = validate_groq_key(
    os.environ["GROQ_API_KEY"]
)
print(message)

Method 4: JavaScript/Node.js Validation

import Groq from "groq-sdk";

async function validateGroqKey(apiKey) {
  try {
    const groq = new Groq({ apiKey });
    
    // Test with minimal completion
    const completion = await groq.chat.completions.create({
      model: "mixtral-8x7b-32768",
      messages: [
        { role: "user", content: "test" }
      ],
      max_tokens: 5
    });
    
    return {
      valid: true,
      message: "Valid Groq API key"
    };
  } catch (error) {
    if (error.status === 401) {
      return { valid: false, message: "Invalid API key" };
    }
    return { valid: false, message: error.message };
  }
}

// Usage
const result = await validateGroqKey(process.env.GROQ_API_KEY);
console.log(result);

Common Groq API Key Errors

Error: "Groq API key not working" (401 Unauthorized)

Causes:

• API key format incorrect (must start with gsk_)
• Key has been revoked or deleted
• Extra spaces in key
• Using wrong environment key

Solutions:

1. Verify format: gsk_[32 characters]
2. Re-copy from Groq Console
3. Generate new API key
4. Remove leading/trailing whitespace

# Clean and validate key
api_key = os.environ["GROQ_API_KEY"].strip()
if not api_key.startswith("gsk_"):
    raise ValueError("Invalid Groq key format")

Error: Rate Limit Exceeded (429)

Causes:

• Exceeding free tier limits
• Too many concurrent requests
• Burst limit reached

Solutions:

import time
from groq import RateLimitError

def groq_with_retry(client, model, messages, max_retries=3):
    """Call Groq with exponential backoff"""
    for attempt in range(max_retries):
        try:
            return client.chat.completions.create(
                model=model,
                messages=messages
            )
        except RateLimitError:
            if attempt < max_retries - 1:
                wait_time = 2 ** attempt
                print(f"Rate limited, waiting {wait_time}s...")
                time.sleep(wait_time)
            else:
                raise

Error: Model Not Available

Causes:

• Model name typo
• Model temporarily unavailable
• Using deprecated model

Solutions:

def list_available_groq_models(api_key):
    """List all available Groq models"""
    client = Groq(api_key=api_key)
    models = client.models.list()
    
    available = []
    for model in models.data:
        available.append({
            'id': model.id,
            'owned_by': model.owned_by,
            'active': model.active
        })
    
    return available

# Usage
models = list_available_groq_models(os.environ["GROQ_API_KEY"])
for m in models:
    print(f"✅ {m['id']} - Active: {m['active']}")

Groq API Key Format

Standard Format: gsk_[32 alphanumeric characters]

Example: gsk_a1b2c3d4e5f6g7h8i9j0k1l2m3n4o5p6

Components:

• gsk_ - Groq secret key prefix
• 32 characters - Unique key identifier
• Case-sensitive alphanumeric

Groq Models Available

| Model | Model ID | Context Length | Speed | |-------|----------|----------------|-------| | Mixtral 8x7B | mixtral-8x7b-32768 | 32,768 tokens | Ultra-fast | | Llama 3 70B | llama3-70b-8192 | 8,192 tokens | Fastest | | Llama 3 8B | llama3-8b-8192 | 8,192 tokens | Instant | | Gemma 7B | gemma-7b-it | 8,192 tokens | Very fast |

Validate Model Access

def test_groq_models(api_key):
    """Test which Groq models are accessible"""
    client = Groq(api_key=api_key)
    
    models_to_test = [
        "mixtral-8x7b-32768",
        "llama3-70b-8192",
        "llama3-8b-8192",
        "gemma-7b-it"
    ]
    
    working_models = []
    
    for model in models_to_test:
        try:
            client.chat.completions.create(
                model=model,
                messages=[{"role": "user", "content": "test"}],
                max_tokens=1
            )
            working_models.append(model)
            print(f"✅ {model}")
        except Exception as e:
            print(f"❌ {model}: {str(e)}")
    
    return working_models

Best Practices for Groq API Keys

1. Secure Key Storage

# Never hardcode keys
# ❌ Bad
groq_key = "gsk_a1b2c3d4e5f6g7h8i9j0k1l2m3n4o5p6"

# ✅ Good - Use environment variables
import os
groq_key = os.environ["GROQ_API_KEY"]

# ✅ Better - Use secret management
from azure.keyvault.secrets import SecretClient
from azure.identity import DefaultAzureCredential

def get_groq_key():
    credential = DefaultAzureCredential()
    client = SecretClient(
        vault_url="https://your-vault.vault.azure.net/",
        credential=credential
    )
    return client.get_secret("groq-api-key").value

2. Implement Caching

from functools import lru_cache
from datetime import datetime, timedelta

# Cache validation results
validation_cache = {}

def validate_groq_with_cache(api_key: str) -> bool:
    """Validate with 1-hour cache"""
    cache_key = api_key[:10]  # Use prefix as cache key
    
    if cache_key in validation_cache:
        timestamp, is_valid = validation_cache[cache_key]
        if datetime.now() - timestamp < timedelta(hours=1):
            return is_valid
    
    is_valid, _ = validate_groq_key(api_key)
    validation_cache[cache_key] = (datetime.now(), is_valid)
    
    return is_valid

3. Monitor Usage

import logging

class GroqUsageMonitor:
    """Monitor Groq API usage"""
    
    def __init__(self, api_key):
        self.client = Groq(api_key=api_key)
        self.request_count = 0
        self.total_tokens = 0
        
    def monitored_completion(self, model, messages, **kwargs):
        """Track usage metrics"""
        response = self.client.chat.completions.create(
            model=model,
            messages=messages,
            **kwargs
        )
        
        self.request_count += 1
        self.total_tokens += response.usage.total_tokens
        
        logging.info(f"Groq Request #{self.request_count}")
        logging.info(f"Tokens: {response.usage.total_tokens}")
        logging.info(f"Total tokens used: {self.total_tokens}")
        
        return response

# Usage
monitor = GroqUsageMonitor(os.environ["GROQ_API_KEY"])
response = monitor.monitored_completion(
    model="mixtral-8x7b-32768",
    messages=[{"role": "user", "content": "Hello"}]
)

4. Key Rotation Strategy

#!/bin/bash
# Rotate Groq API key with zero downtime

# 1. Generate new key in Groq Console
echo "Generate new key at: https://console.groq.com/keys"

# 2. Validate new key
NEW_KEY="gsk_..."
curl -s https://api.groq.com/openai/v1/models \
  -H "Authorization: Bearer ${NEW_KEY}" \
  | jq -e '.data | length > 0'

if [ $? -eq 0 ]; then
    echo "✅ New key is valid"
else
    echo "❌ New key validation failed"
    exit 1
fi

# 3. Deploy new key to staging
kubectl set env deployment/app \
  GROQ_API_KEY="${NEW_KEY}" \
  -n staging

# 4. Test in staging
sleep 30
kubectl logs -n staging deployment/app --tail=100 | grep "Groq.*success"

# 5. Deploy to production
kubectl set env deployment/app \
  GROQ_API_KEY="${NEW_KEY}" \
  -n production

# 6. Delete old key after 24 hours
echo "Delete old key in Groq Console after confirming new key works"
