Environment Variables

Create a .env file in your project root:

​
Basic Setup

import { Continum } from '@continum/sdk';

const continum = new Continum({
  continumKey: process.env.CONTINUM_KEY,
  openaiKey: process.env.OPENAI_API_KEY
});

// Make your first call - specify sandbox per call
const response = await continum.llm.openai.gpt_4o.chat({
  messages: [
    { role: 'user', content: 'Hello, world!' }
  ],
  sandbox: 'your-sandbox-slug'  // Sandbox is required for auditing
});

console.log(response.content);

​
TypeScript Support

The SDK is written in TypeScript and includes full type definitions: 
import { Continum, ChatResult, ContinumConfig } from '@continum/sdk';

const config: ContinumConfig = {
  continumKey: process.env.CONTINUM_KEY!,
  openaiKey: process.env.OPENAI_API_KEY,
  guardianEnabled: true
};

const continum = new Continum(config);

const response: ChatResult = await continum.llm.openai.gpt_4o.chat({
  messages: [{ role: 'user', content: 'Hello' }],
  sandbox: 'your-sandbox-slug'  // Specify sandbox for this call
});

​
Verify Installation

Test your setup with this simple script: 
import { Continum } from '@continum/sdk';

async function test() {
  const continum = new Continum({
    continumKey: process.env.CONTINUM_KEY,
    openaiKey: process.env.OPENAI_API_KEY,
    defaultSandbox: 'your-sandbox-slug'
  });

  try {
    const response = await continum.llm.openai.gpt_4o.chat({
      messages: [{ role: 'user', content: 'Say hello' }]
    });
    
    console.log('✅ SDK working!');
    console.log('Response:', response.content);
  } catch (error) {
    console.error('❌ Error:', error.message);
  }
}

test();
Run it: 
npx tsx test.ts
# or
node test.js

Common Issues

​
Missing API Key

Error: Missing continumKey in configuration
Solution: Ensure CONTINUM_KEY is set in your environment variables.

​
Invalid API Key

Error: Invalid API key
Solution: Verify your API key in the dashboard.

​
Sandbox Not Found

Error: Sandbox "my-sandbox" not found
Solution: Create the sandbox in the dashboard first, or use an existing sandbox slug.

​
Provider Key Missing

Error: OpenAI API key required for this call
Solution: Ensure the provider’s API key is configured: 
const continum = new Continum({
  continumKey: process.env.CONTINUM_KEY,
  openaiKey: process.env.OPENAI_API_KEY  // Add this
});
