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: 'user', content: 'Say "connection verified" and nothing else.' },
    ],
  });
  console.log('Status:', response.message?.content?.[0]?.text);
}

verify().catch(console.error);

Step 4: Verify Connection (Python)

import cohere
import os

co = cohere.ClientV2(api_key=os.environ.get("CO_API_KEY"))

response = co.chat(
    model="command-a-03-2025",
    messages=[
        {"role": "user", "content": "Say 'connection verified' and nothing else."}
    ],
)
print("Status:", response.message.content[0].text)

Error Handling

Error	Cause	Solution
`CohereApiError: invalid api token`	Wrong or expired key	Regenerate at dashboard.cohere.com
`CohereConnectionError`	Network blocked	Ensure HTTPS to `api.cohere.com` allowed
`429 Too Many Requests`	Trial rate limit hit	Wait 60s or upgrade to production key
`MODULE_NOT_FOUND cohere-ai`	Package not installed	Run `npm install cohere-ai`

SDK Auto-Detection

The SDK reads

CO_API_KEY

automatically if set. You can skip the

token

param:

// Auto-reads CO_API_KEY from environment
const cohere = new CohereClientV2();

Next Steps

After successful auth, proceed to

cohere-hello-world

for your first real API call.
