Description
Build a smart crawler with agentic capabilities that extracts structured data from any website — all powered via n8n, OpenAI, and Supabase.
Perfect for anyone needing targeted info (like social links, contact pages, etc.) across websites without manual digging.
🔹 How It Works:
✅ 🌍 Input URL – Provide any website
✅ 🔗 Link Collection – The AI agent fetches all available links using the URLs Tool
✅ 📄 Text Analysis – It then scrapes and analyzes text content using the Text Tool
✅ 🧠 AI Agent Logic – The OpenAI-powered agent interprets the structure and finds the info you need (e.g., social links, emails, contact details)
✅ 📦 Store Output – Results are saved in Supabase (or your preferred DB) for later use
💼 Use Cases:
🔗 Social Media Link Extraction – Pull all available social handles from websites
📬 Contact Info Mining – Auto-fetch emails, phone numbers, and contact forms
🌐 Lead Enrichment – Feed company URLs and get back useful business info
📰 Content Harvesting – Extract text, page titles, or custom schema-based content
🔍 Niche Site Crawling – Explore multiple subpages to locate specific information
🧠 Why It’s Smart:
⚙️ Agentic Navigation – The AI crawls subpages like a human
🛠️ Modular Tools – Customize schema, prompt, and tools to extract what you need
🔄 Self-Looping Logic – It can iterate across linked pages autonomously
🧠 LLM Reasoning – Understands context to find relevant data, not just keywords
🧰 Works with Supabase – Easy to extend into full-stack workflows with SQL or RPC triggers
🔧 Level of Effort:
🟡 Moderate – Basic setup takes ~15–20 minutes, advanced config (like custom JSON schema) adds depth
🧩 You’ll Need:
🔐 OpenAI API Key (for the agent’s reasoning and schema-based extraction)
🗂️ Supabase Project (to store input URLs + extracted results)
🧠 Prompt + JSON Schema (tell the agent what data to return)
🌍 Website URLs (manually or from a trigger-based source like Airtable, Notion, CSV)
💡 Customization Tip:
Want to extract contact info and blog post metadata? Duplicate the crawler and tweak its schema. You can even use the outputs to auto-populate CRMs, send emails, or track site changes via alerts.
