Mistral AI Install & Auth

Overview

Set up Mistral AI SDK and configure authentication credentials for chat completions, embeddings, and function calling.

Prerequisites

Node.js 18+ or Python 3.9+
Package manager (npm, pnpm, yarn, or pip)
Mistral AI account with API access
API key from Mistral AI console (https://console.mistral.ai/)

Instructions

Step 1: Install SDK

Node.js (TypeScript/JavaScript)

# npm
npm install @mistralai/mistralai

# pnpm
pnpm add @mistralai/mistralai

# yarn
yarn add @mistralai/mistralai

Python

pip install mistralai

Step 2: Configure Authentication

Environment Variables (Recommended)

# Set environment variable
export MISTRAL_API_KEY="your-api-key"

# Or create .env file
echo 'MISTRAL_API_KEY=your-api-key' >> .env

Using dotenv (Node.js)

npm install dotenv

import 'dotenv/config';

Step 3: Verify Connection

TypeScript

import Mistral from '@mistralai/mistralai';

const client = new Mistral({
  apiKey: process.env.MISTRAL_API_KEY,
});

async function testConnection() {
  try {
    const models = await client.models.list();
    console.log('Connection successful! Available models:');
    models.data?.forEach(model => console.log(`  - ${model.id}`));
  } catch (error) {
    console.error('Connection failed:', error);
  }
}

testConnection();

Python

import os
from mistralai import Mistral

client = Mistral(api_key=os.environ.get("MISTRAL_API_KEY"))

def test_connection():
    try:
        models = client.models.list()
        print("Connection successful! Available models:")
        for model in models.data:
            print(f"  - {model.id}")
    except Exception as e:
        print(f"Connection failed: {e}")

test_connection()

Output

Installed SDK package in node_modules or site-packages
Environment variable or .env file with API key
Successful connection verification showing available models

Error Handling

Error	Cause	Solution
401 Unauthorized	Invalid or missing API key	Verify key at console.mistral.ai
429 Too Many Requests	Rate limit exceeded	Implement backoff, check quota
Network Error	Firewall or connectivity	Ensure HTTPS to api.mistral.ai allowed
Module Not Found	Installation failed	Run `npm install` or `pip install` again

Examples

TypeScript Client Initialization

import Mistral from '@mistralai/mistralai';

const client = new Mistral({
  apiKey: process.env.MISTRAL_API_KEY,
  // Optional: custom timeout
  timeout: 30000,
});

export default client;

Python Client Initialization

import os
from mistralai import Mistral

client = Mistral(
    api_key=os.environ.get("MISTRAL_API_KEY"),
    # Optional: custom timeout
    timeout=30.0,
)

Validate API Key Format

function validateMistralApiKey(key: string): boolean {
  // Mistral API keys are UUIDs or specific format
  return key.length > 20 && !key.includes(' ');
}
