Cohere Install & Auth

Overview

Set up the Cohere SDK (v2) and configure authentication for Chat, Embed, Rerank, and Classify endpoints.

Prerequisites

• Node.js 18+ or Python 3.10+
• Package manager (npm, pnpm, or pip)
• Cohere account at dashboard.cohere.com
• API key from Cohere dashboard (trial keys are free, production keys require billing)

Instructions

Step 1: Install SDK

# Node.js / TypeScript
npm install cohere-ai

# Python
pip install cohere

Step 2: Configure API Key

# Set environment variable
export CO_API_KEY="your-api-key-here"

# Or create .env file (add .env to .gitignore!)
echo 'CO_API_KEY=your-api-key-here' >> .env

Key types:

• Trial key — free, rate-limited (5-20 calls/min per endpoint, 1000/month others)
• Production key — metered billing, 1000 calls/min all endpoints, unlimited monthly

Step 3: Verify Connection (TypeScript)

import { CohereClientV2 } from 'cohere-ai';

const cohere = new CohereClientV2({
  token: process.env.CO_API_KEY,
});

async function verify() {
  const response = await cohere.chat({
    model: 'command-a-03-2025',
    messages: [
      { role: , :  },
    ],
  });
  .(, response.?.?.[]?.);
}

().(.);
