Important
Treat your API keys like passwords. Keep them secret — use only on the server side.

Remember to keep your API key secret! Your Langbase API key is sever side only. Never share it or expose it in client-side code like browsers or apps. For production requests, route them through your own backend server where you can securely load your API key from an environment variable or key management service.

All API requests should include your API key in an Authorization HTTP header as follows:

Authorization: Bearer LANGBASE_API_KEY

With Langbase SDK, you can set your API key as follows:

import {Langbase} from 'langbase';

const langbase = new Langbase({
	apiKey: process.env.LANGBASE_API_KEY
});
