Scrape and Analyze Websites with Custom Prompts using Gemini, Apify, and LangChain

🔍 AI-Powered Website Prompt Executor (Apify + OpenRouter)

This workflow combines the power of Apify and OpenRouter to scrape website content and execute any custom prompt using AI. You define what you want — whether it’s extracting contact details, summarizing content, collecting job offers, or anything else — and the system intelligently processes the site to give you results.

🚀 Overview

This workflow allows you to:

Input a URL and define a prompt.
Scrape the specified number of pages from the website.
Process each page’s metadata and Markdown content.
Use AI to interpret and respond to the prompt on each page.
Aggregate and return structured output.

🧠 How It Works

{
  "enqueue": true,
  "maxPages": 5,

}
