import { ADS4GPTsToolkit } from 'ads4gpts-langchain';

// Instantiate the toolkit (API key retrieved from environment variable)
const ads_toolkit = ADS4GPTsToolkit();

const ads_tools = ads_toolkit.getTools();

// Retrieve ads using one of the tools
const chatArgs = {
    context: 'Looking for the latest smartphone deals',
    num_ads: 1,

const ads = await ads_tools[0]._call(chatArgs);
console.log(ads);
