Solves reCAPTCHA to access the targeted product page.\n3. Retrieves and extracts data from the product page for further analysis.\n4. Compares newly fetched data with previously stored data to detect changes.\n5. Determines if changes occurred and prepares alerts if needed.\n6. Sends responses based on data analysis through designated channels.\n\n### Setup steps\n\n- [ ] Configure scheduled trigger interval in 'Every 6 Hours' node.\n- [ ] Set target website details in 'Set Target Config [Schedule]'.\n- [ ] Configure reCAPTCHA solver with API key in 'Solve reCAPTCHA v3' nodes.\n- [ ] Set up Webhook URL and path in 'Webhook Trigger'.\n- [ ] Define alert criteria and destination in 'Build Alert' nodes.\n\n### Customization\n\nAdjust the extraction pattern in 'Extract Data' nodes to fit specific product details.",
