Extract & process Q&A from URLs with Airtop, OpenRouter AI & Safety Guardrails

Transform your Telegram bot into a secure content analyzer: send any URL, and get safe, structured Q&A extractions with AI-powered safety checks and web search capabilities. 📋 What This Template Does This workflow activates when a user sends a valid URL to your Telegram bot. It extracts questions and answers from the webpage using Airtop, applies NSFW and PII guardrails to ensure safe content, then uses an OpenRouter AI agent (with optional Tavily search) to generate and send a concise response. If guardrails fail, it alerts the user instead. - Filters for valid URLs only to prevent unnecessary processing - Extracts structured Q&A from documents or forms - Enforces safety checks for harmful or private content - Supports web searches for enhanced responses when needed 🔧 Prerequisites - A Telegram bot created via @BotFather - Accounts with Airtop, OpenRouter, and Tavily 🔑 Required Credentials Telegram API Setup 1.
