Quick Reference

Authentication Setup

Get your API key: Visit NVIDIA API Catalog to obtain your API key.

# Set environment variable
export NVIDIA_API_KEY="nvapi-your-key-here"

# Python - Using environment variable
import os
api_key = os.environ.get("NVIDIA_API_KEY")

Basic Chat Completion (Python)

import requests

url = "https://integrate.api.nvidia.com/v1/chat/completions"
headers = {
    "Authorization": f"Bearer {api_key}",
    "Content-Type": "application/json"
}

payload = {
    "model": "meta/llama3-70b-instruct",
    "messages": [
        {"role": "user", "content": "Explain quantum computing in simple terms"}
    ],
    "max_tokens": 150,
    "temperature": 0.7
}

response = requests.post(url, json=payload, headers=headers)
result = response.json()
print(result["choices"][0]["message"]["content"])

Streaming Chat Response

import requests
import json

url = "https://integrate.api.nvidia.com/v1/chat/completions"
headers = {
    "Authorization": f"Bearer {api_key}",
    "Content-Type": "application/json"
}

payload = {
    "model": "mistralai/mixtral-8x7b-instruct",
    "messages": [{"role": "user", "content": "Write a short story"}],
    "stream": True
}

response = requests.post(url, json=payload, headers=headers, stream=True)

for line in response.iter_lines():
    if line:
        line = line.decode('utf-8')
        if line.startswith('data: '):
            data = line[6:]
            if data != '[DONE]':
                chunk = json.loads(data)
                content = chunk["choices"][0]["delta"].get("content", "")
                print(content, end="", flush=True)

OpenAI-Compatible Integration

from openai import OpenAI

# Drop-in replacement for OpenAI client
client = OpenAI(
    base_url="https://integrate.api.nvidia.com/v1",
    api_key=api_key
)

completion = client.chat.completions.create(
    model="meta/llama3-70b-instruct",
    messages=[{"role": "user", "content": "Hello!"}],
    temperature=0.5,
    max_tokens=100
)

print(completion.choices[0].message.content)

Code Generation Example

# Using code-specialized models
payload = {
    "model": "bigcode/starcoder2-15b",
    "messages": [
        {"role": "system", "content": "You are an expert programmer."},
        {"role": "user", "content": "Write a Python function to calculate Fibonacci numbers"}
    ],
    "temperature": 0.2,  # Lower temperature for code generation
    "max_tokens": 500
}

response = requests.post(url, json=payload, headers=headers)
code = response.json()["choices"][0]["message"]["content"]

Multi-Turn Conversation

conversation = [
    {"role": "system", "content": "You are a helpful assistant."},
    {"role": "user", "content": "What is machine learning?"},
]

# First response
response1 = requests.post(url, json={"model": "meta/llama3-70b-instruct", "messages": conversation}, headers=headers)
assistant_reply = response1.json()["choices"][0]["message"]["content"]

# Continue conversation
conversation.append({"role": "assistant", "content": assistant_reply})
conversation.append({"role": "user", "content": "Can you give me an example?"})

response2 = requests.post(url, json={"model": "meta/llama3-70b-instruct", "messages": conversation}, headers=headers)

JavaScript/Node.js Example

const axios = require('axios');

const url = 'https://integrate.api.nvidia.com/v1/chat/completions';
const apiKey = process.env.NVIDIA_API_KEY;

async function chatCompletion() {
  const response = await axios.post(url, {
    model: "mistralai/mistral-7b-instruct",
    messages: [
      { role: "user", content: "What are the benefits of renewable energy?" }
    ],
    max_tokens: 200
  }, {
    headers: {
      'Authorization': `Bearer ${apiKey}`,
      'Content-Type': 'application/json'
    }
  });

  console.log(response.data.choices[0].message.content);
}

chatCompletion();

cURL Example

curl https://integrate.api.nvidia.com/v1/chat/completions \
  -H "Authorization: Bearer $NVIDIA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "meta/llama3-8b-instruct",
    "messages": [
      {"role": "user", "content": "Hello, how are you?"}
    ],
    "max_tokens": 50,
    "temperature": 0.7
  }'

Error Handling

try:
    response = requests.post(url, json=payload, headers=headers)
    response.raise_for_status()  # Raise exception for 4xx/5xx status codes
    result = response.json()
except requests.exceptions.HTTPError as e:
    if response.status_code == 401:
        print("Authentication failed. Check your API key.")
    elif response.status_code == 429:
        print("Rate limit exceeded. Please slow down requests.")
    else:
        print(f"HTTP Error: {e}")
except requests.exceptions.RequestException as e:
    print(f"Request failed: {e}")

Best Practices

API Key Security

• Never commit API keys to version control
• Use environment variables for key storage
• Rotate keys regularly for security
• Monitor usage to detect unauthorized access

Parameter Tuning

• Temperature: Lower (0.1-0.3) for factual/code, higher (0.7-1.0) for creative
• Max tokens: Set appropriate limits to control costs and response length
• Top-p: Alternative to temperature for controlling randomness
• Streaming: Enable for better user experience in interactive applications

Error Handling

• Implement retry logic with exponential backoff
• Handle rate limits gracefully (HTTP 429)
• Validate responses before using in production
• Log errors for debugging and monitoring

Model Selection

• Small models (7B-8B): Fast, cost-effective for simple tasks
• Medium models (13B-34B): Balance of performance and efficiency
• Large models (70B+): Best quality for complex reasoning and generation
